Sheila, I LOVE the microwave steamer. I steam chicken breast and fish filets in it....That kind of meat is fine steamed, but I want my beef browned. Just looks better, so I bake it in the oven.
Vegetables in the steamer are marvelous. One needs not add a lot of spices to the veggies to jazz them up. Everything tastes so fresh and good. The veggies keep those lovely colors and just "looks good enough to eat". If it were not for Milt's bacon for breakfasf.....I'd NEVER use the cooktop of the stove. 
I use the steamer daily. I do find that I like fresh veggies far better than any frozen ones. Frozen ones end up "watery tasting", and steaming from fresh gives you the full benefit of the vegetable flavor!
Happy RVing all!!
