pasta + vegetables

I watched a friend make this last night and would like to replicate it some time. It was richer than I'd expect.

chopped onion + garlic
sliced vegetables: bell pepper, broccoli, snow peas, grape tomatoes
pasta
milk
breadcrumbs
cheese

Saute onion and garlic with some Italian seasonings, then add other veggies. Toward the end--some grape tomatoes.
Then, add milk(mixed with buttermilk, this time) (and I think also some vegennaise?)and cook for a bit. Then add "Italian" breadcrumbs. And add some cheese (he used grated Havarti.) Serve over pasta and with some chicken or other meat for protein.
