Prep time: 20 minutes
1. Preheat oven to 350°F.
2. Spray both sides of mushrooms with non-stick cooking spray and place with cap side down on a baking sheet. Brush 1⁄2 teaspoon olive oil evenly over each mushroom. Bake for 5-10 minutes or until tender when pierced with a fork.
3. Heat a large non-stick skillet over medium-high heat. Remove skillet from heat and spray with non-stick cooking spray (being very careful not to spray near a gas flame). Sauté bell peppers, onion, garlic and red pepper flakes for 5 minutes or until bell peppers are tender. Stir frequently.
4. Remove the skillet from heat and stir in tomatoes and basil.
5. Rinse spinach leaves and shake off excess water. Do not dry with paper towels. Top each mushroom with spinach leaves. Carefully spoon 1⁄2 cup of the pepper mixture on each. Sprinkle with cheese and bake for 6-7 minutes, or until cheese begins to melt.
Brushing a small amount of oil on Portobello mushrooms before baking or broiling prevents the mushrooms from getting a “leathery” texture.
