salt and pepper, olive oil is the main flavor along with the delicious super fresh veggies. I don't like to overpower them. Add minced garlic but not powder. ooh maybe a little fresh parm over the top!
I like cabbage with onions, garlic, carrots and tomatoes; broccoli with cauliflower, leeks, garlic and baby carrots; green beans with garlic, onion and carrots; corn with red sweet peppers...
Gee, there are so many... a few combinations that springs to my mind right now...
bell peppers and onions are always lovely together, though both of them go well with so many other things.
aubergene/egg plant with tomatoes, like "aubergene parmigiano" and pasta alla norma,
radicchio and carrots, the contrast of the "pleasant bitterness" that of radicchio and the sweetness of carrot can be also very nice...
We love peas and mushrooms, my kids love cold baby carrots with cold small whole green beans, with a mix of fresh herbs like chives,thyme, oil and vinegar, garlic and then just serve at room temp.Broccoli and cauliflower with cheese sauce. Onions and garlic with most everything. Diced tomatoes and cucumbers, tomatoe and avocado layederd on a sandwich, baby snap peas and water chestnuts, a mix of zucchini and yellow crookneck or yellow zucchini saute in butter,salt and pepper then sprinkle with parm..
Can't think of anymore right now tho.
