Dice a few bacon strips and cook them. Saute asparagus spears or broccoli florets in the grease until al dente. Toss with the bacon bits and a little dijon and white wine vinegar.
Saute julienned onions and sliced mushrooms in butter. Serve over meat.
Roast brussels sprouts, mushrooms, onion, cauliflower, etc, coated with olive oil and herbs or a bit of balsamic vinegar.
Make soup with lots of veggies in it.
Make mashed cauliflower (just like you'd make mashed potatoes). It's great with roasted garlic blended in.
And, of course, serve with plenty of meat!
