Spray large skillet with cooking spray; heat over medium-high heat. Add zucchini; cook 2 to 3 minutes or until tender, stirring occasionally.
Add ravioli, drained tomatoes and garlic powder; cook 3 to 5 minutes or until hot, stirring occasionally. Sprinkle with cheese, cover and cook 1 to 2 minutes or until cheese melts.
Picky eaters? You may make the recipe without the zucchini or use a vegetable your family likes. Shredded carrot or chopped bell peppers are two vegetables to consider.
