Cauliflower, broccoli, a red pepper past it prime, mushrooms, carrots, asparagus, and a tablespoon of walnuts, sauteed in a tablespoon of olive oil and seasoned with salt and pepper. Cook it til you're bored. Include onions and add gf soy sauce and serve over rice for a more traditional stirfry. Personally, I'm working on minimizing grains, and the great taste is driven by the veggies. Make a lot and enjoy!
1) Buy them already cut up if possible. Produce Junction sells bags of broccoli florets. It's easy to find mushrooms already sliced. A nutritionist friend of mine suggested this to me a long time ago, and I felt strangely freed from the guilt of not doing all the chopping myself.
2) Since many fresh veggies are fine eaten raw, chop them big (which goes much faster) and cook them longer or shorter depending on your patience level. This won't work for folks who have trouble with raw veggies, but I find them most enjoyable when there is still some structure left to them. Not crunchy exactly, but that place between crunchy and soft. "Cook it til you're bored" is a common phrase in our house for recipes.
3) See my blog post on Beans and Greens (another common go-to dinner in my house) for other ideas for seasonings to keep things interesting. Keep it easy!
