Steaming mushrooms is simple and delicious. Slice up a pound of portobellos and sprinkle on them some thyme or paprika. Steam them for about twenty minutes, or until they're tender. Simple and delicious! Eat this with some steamed veggies, like asparagus, peas, or broccoli. Sugar snap peas go great with mushrooms.
Eggplant is one of those foods a lot of people avoid simply because they don't know what to do with it. Cut your eggplant into 1/2 inch thick strips. Steam it, either plain or with a couple thinly sliced cloves of garlic. What's going to make or break eggplant is the sauce you serve it with. Look at some simple Asian sauces that you can serve this with--consider garlic sauces, red wine vinegar based sauces, and brown sauces. Look for ones that use little to no oil. Heat up whatever sauce you make and pour this over the steamed eggplant. Consider also steaming some zucchini to mix in.
For any of these ideas, serve them with some fresh steamed vegetables, like asparagus, green beans, broccoli, peas, or carrots. If you have a steamer with multiple baskets, steam a couple different vegetables and season them with things like garlic powder, thyme, rosemary, coarse salt, pepper, or nutritional yeast--either after steaming them, or before.
