Great recipe for lemon squares from Melissa Clark at the NYTimes.
@Consolation : Keebler makes one. I’ve seen them in stores, but have not personally tried:

Could be bleh, could be OK.
OP: I know you’ve already decided, but imo that sort of dinner screams a strawberry shortcake dessert! With lots of light, fluffy whipped cream! If you go for the lemon squares,or whatever else, enjoy!
I’ve made fruit kabobs with melon, berries
Strawberry shortcake is at its best when the biscuit has lemon rind, and is straight out of the oven buttered lightly. Which makes it tough to serve at its peak. 
That’s the shortbread crust, Keebler, which is better than the graham cracker crust, imho.
Now tonight someone talked me into making a strawberry trifle, with angel food cake. Yummy, but I prefer the pie.
I recently saw a nectarine galette recipe that called for a bunch of unpeeled nectarines roughly chopped, a couple of tablespoons of sugar and flour, and a Trader Joes pie crust (pre-rolled).
You just unfold the pie crust onto a baking dish, dump the nectarine mixture on top, grate a little bit of lemon zest, and loosely wrap the dough around the pile of nectarines.
You can brush the dough with egg and heavy cream for browning but I’d skip that step.
I break my no-cooking rule in summer for stone-fruit desserts, and not having to roll out temperamental pie crust is a big positive to me. Will be trying this one!
Since a number here like lemon, just sometime try that Martha recipe for Lemon Mousse. (Originally is from some other source, I first made it decades ago.) It’s elegant and a nice surprise.
Btw, it’s an old recipe from some once famous restaurant to put sour cream and brown sugar over grapes.
Grape salad! The totally controversial entry from the NY Times for regional Thanksgiving specialties! The Internet exploded when the NY Times claimed that grape salad – Thompson grapes, sour cream and brown sugar – was a traditional Thanksgiving dish in Minnesota. Midwesterners of all stripes claimed an anti-midwestern bias by the NY Times. Recast as a modification of a chic French picnic good, it has much more cache!
PS Seriously! Google grape salad!
If I was from MN, I’d rather claim grape salad as a regional dish than Lutefisk!
I just wouldn’t call it “Grape Salad.” Doctor up the name, for the impression. Maybe “Soleil Vert.”
Better: I just saw some call the fancy version “Grapes Romanov.”
