This weekend I did boneless chicken breasts w/out skin in the crockpot along with a jar of green salsa. Cooked for hours and then shredded the chicken while in the pot. The chicken absorbed much of the liquid and it was truly DELICIOUS!!! Great flavor. A spice taste but not SPICY! Served in freshly cooked flour tortillas (Costco) with queso fresco, diced tomato/fresh banana pepper, onion, jalapeno, sour cream, cilantro - SO, SO good!
The green salsa really made it GOOD!!
Ramen & boiling water
Bread and butter!! 
Or better yet, a pot of melted Gruyere and a bunch of green beans. After having these 2 2-ingredient dishes, we were stuffed, so we ordered salads. 
I find these recipes silly. Quick, easy recipes, great. Focusing on whether there are 2 or 5 or 7 ingredients, pointless. This information doesn’t actually tell you whether the recipe is quick and easy. Baguettes have 3 ingredients and are a hundred times harder to make than a crock-pot chili (meat, onion, beans, tomato soup, chili powder). Does that chili get harder to make if you add garlic and green peppers and a can of garbanzos? That’s not what makes cooking hard or time-consuming.
Novice cooks should worry about about recipes with multiple steps, endless monitoring (risotto!), little margin for error, or split-second timing. I’ve been cooking for my family for 30 years, but last night I left the scallops on the stove a hair too long and they got rubbery. Tricky little buggers. Two ingredients: scallops and olive oil!
Absolutely Hanna! I would also pick and choose what 2-ingredient recipes make sense for me just as I would a multi ingredient (or multi-step) other recipe!
Here’s a SUPER EASY, tasty 3-ingredient favorite in our house:
Jalapeno grilled cheese sandwiches
Assemble the grilled sandwich like you normally would, but sprinkle some chopped up jalapenos on the cheese slice.
Melt a little pat of butter in a pan. Put the assembled sandwich in the melted butter and cook till lightly brown on the bottom.
Repeat cooking procedure for the other side of the sandwich.
Boiled vegs. Water and vegs. 2 ingredients. I think it’s healthy. Not sure about the tasty part.
It’s not two ingredients but it is remarkably easy to make and so delicious. Also the recipe is so simply it’s easy to remember by heart so it kinda falls into the category.
Amazing Amish Cinnamon Bread: (makes 2 loaves) Batter: 1 C butter, softened, 2 C sugar, 2 eggs, 2 C buttermilk, 4 C flour mixed with 2 tsp baking soda. Add the ingredients in listed order. Pour half the batter into the pans then add half of this cinnamon/sugar mixture of 2/3 C sugar and 2 tsp cinnamon onto poured batter(BTW, I double the cinnamon) Add the remaining batter and then top with the remaining sugar/cinnamon mix. Bakes between 45 and 60 min(do the toothpick test).
It smells so good you’re going to want to cut it right away but you MUST, MUST, MUST let it cool in the pan for 20 minutes or it will fall apart.
creme fraiche and bottled spaghetti sauce mix together, poor on top of pasta.
Two ingredients, with an optional third (and maybe a forth)
Take good quality Italian sausage (hot or mild, your choice). Cut into 1" chunks, put into a dutch oven. Cut up as many sweet peppers as you can find (I usually use 5 or 6) into big chunks, add to dutch oven. Place over medium low heat. Cook for about an hour, stirring occasionally, until the peppers are soft and have “melted” into a sauce. Great just as is, but if you want you can serve it over wide egg noodles or papperdelle. If you want to be fancy you can sprinkle some chopped parsley on top.
I use hot sausage and red, yellow and orange peppers. I avoid green peppers because they get bitter when cooked this long. This actually on old Italian dish, and is good with or without the pasta.
I forgot and it is important. Cook it with the lid on the pan.
Lol, Dr. Google. Good one! How about roasting? Cut up veggies and olive oil? 
My SUPER EASY 4-ingredient Corn Soup
In a sauce pan, combine the chicken broth concentrate, 1 can of water, the creamed corn.
Bring to a boil, then reduce heat so it’s not bubbling.
Gently stir in the beaten egg. Don’t over-stir, otherwise the egg pieces get too little.
Stir in a little chopped fresh cilantro.
A little shake of white pepper is nice.
DS told us that he and roommates hosted a picnic using their new bbq grill. For the vegetarian friends they grilled halved peppers with egg inside plus cheese. I had never heard to that, but per a quick google search there are many variations.
