My D is on her own for the first time in her life. So far so good. I expect she will get busy and cooking will have to be simple and fast. Is there a cookbook for fast and nutricious meals?
Try Hungry Girl series of cookbooks. There should be plenty of vegetarian recipes in them. Or check out her website!
Moosewood is the bible for many. Mark Bittman has one and his cookbooks are generally very good.
Jeanne Lemlin’s “Quick Vegetarian Pleasures” and “Simple Vegetarian Pleasures.” I don’t know if they’re still available but I like both.
I was going to say: Anything by moosewood.
remind her that she can put her ingrediants in a Google search adding “vegetarian”.
I was a vegetarian for 34 years and a vegan for one. I raised my kids vegetarian,
About 5 years ago began cooking meat for H for health reasons. I still prefer Veggie but
still cannot get over how fast a meat meal is to cook.
When I was single and vegetarian I would make a family size meal and break it down to 1-2 servings.
A great casserole can take 1.5 hours to make. Moosewood is great but an old one “Horn of the Moon”
was also a standby
I’m not going to lie. Many of us got cookbooks when we started living on our own. I don’t know anyone who uses them. We all get our recipes online.
Just something to consider.
@romanigypsyeyes, do you print recipes or perch your computer in the kitchen? I do like being able to put a cookbook into a book holder on my kitchen counter.
I don’t cook. (I like my family… I don’t want to kill them!) But my housemate and spouse will either use their laptops or tablets, both of which stand.
Even my mom who held on to her mom’s cookbook for decades and dear life has made the transition to digital. It’s especially helpful since her eyes are going.
I’m 98% online for recipes now save for a few old family recipes. Heavy user of epicurious, all recipes for recipes and pinterest for idea sourcing.
I often get tempted by online recipes, but I do find some cookbooks I keep going back too. There are some really fabulous (and different) vegetarian recipes in Ottolenghi’s Plenty. The followup More Plenty I seem to use less often. I love Bittman, but not his vegetarian cookbook. I started with Moosewood but like Molly Katzen’s Still Life with Menu better now. I do still pull out the two Anna Thomas Vegetarian Epicure books. She has a new Vegi Epi book out organized my menus that looks good, but I don’t own it.
An added benefit to online recipes and one of the reasons I gravitate towards them now are the ratings and reviews. If it doesn’t have a decent average review, I’ll skip it and keep searching. Prevents a waste of ingredients.
How about a magazine subscription to something like Eating Well? Not all recipes are vegetarian, but many are. And you can get it online.
I love the old Vegetarian Epicure books. But I think they are out of print.
Yes, most folks use online recipes a lot…but it’s good to have one go to book for reference. In my opinion.
Any cookbook by Deborah Madison.
Veggie D likes “The Vegetarian Student Cookbook.”
I reach for my phone or iPad probably 90% of the time I’m looking for/using a recipe. I just prop it somewhere in my cooking area. The other 10% would be older recipes from a cookbook or a card.
If she has a Pinterest (and if you have one) you could make a “secret” board (and invite her to participate in it) where you can post vegetarian recipes to it that you think she would like and she would be able to access them!!!
I like cookbooks. I modify recipes as I go along, simplify and adjust seasonings. Hard to do on line.
@mathmom I love PLENTY. I have a copy but their recipes are often time consuming. I am checking out cookbooks mentioned here.
Many online “recipe boxes” have places where you can write notes to yourself of modifications. 
OP, do you feel your D would be more likely to use a cookbook or use online sources for recipes. What the user is more likely to “pick up” is the best option.
I didn’t know you could write notes to onlune recipes. I often have the urge to pick up a sharpie and write on the screen She will do both. She likes to pick up cookbooks and also search for recipes on line.
Last holiday season, I compiled a bunch of vegetarian and clean recipes for the crock-pot from online, put them into a template (also found online), printed them out, put them in those clear plastic sleeves and stuck them in a three-ring binder for my D. It was her favorite gift, and it’s easy for her to take out recipes she found she didn’t care for and add new ones she finds (or that I send her as I run across them).
