Asparagus – plain boiled or steamed. Roasted with olive oil and garlic. Sauteed with bread crumbs.
Broccoli spears or florets – same as asparagus.
So many squashes to make in so many ways.
You can buy kosher brussels sprouts. You can make cooked cabbage in veggie soup and slice the whole cabbage.
Peas and carrots straight from the can. Green beans from the can. Snap peas any way.
That should last you a few weeks.
