A basic cucumber salad with some onion, tomato and vinegar dressing is always great.
This is my go-to summer salad! Chunks of tomato and cucumber with thin-sliced shallot or red onion, salt and let sit for ~20 minutes to release some liquid, drain and add chopped avocado and your favorite canned bean (I like cannellini), dress with black pepper, olive oil and balsamic vinegar.
What my husband and I call "Try Hard Lasagna": we make a double batch of Marcella Hazan's bolognese sauce (non-NYT link), fresh egg pasta, and bechamel. Then those all get layered with mozzarella and parmigianino cheeses into the best lasagna I've ever had.
I actually need to do this soon, because I promised a pregnant friend that I'd make her some in disposable loaf pans for easy post-partum meals.
Also like, the US is mostly sending Ukraine existing supplies. They're "valued at" however many millions of dollars, but the cost to the taxpayer is going to mostly be paying to resupply the US military with what was sent over.
