Ingredients

Vegetable oil cooking spray 

18 large eggs 

2 teaspoons coarse salt 

3/4 teaspoon freshly ground pepper 

1 tablespoon chopped fresh chives 

1 medium zucchini (about 5 ounces), trimmed and cut into 1/8-inch rounds 

4 to 6 white mushrooms, cut lengthwise into 1/8-inch-thick slices 

1 red bell pepper, ribs and seeds removed, flesh cut into 1/8-inch dice 

1 yellow bell pepper, ribs and seeds removed, flesh cut into 1/8-inch dice 

1/2 cup finely grated Gruyere or fontina cheese (about 2 ounces) 

Preparation

Preheat oven to 400 degrees. Lightly coat four 12-cup or two 24-cup mini muffin tins with cooking spray; set aside. Whisk eggs, salt, pepper, and chives in a large bowl; set aside. Put 1 zucchini round, 1 mushroom slice, and about 1 teaspoon bell peppers into each muffin cup. Ladle egg mixture into each cup to fill; sprinkle with cheese, dividing evenly. Bake until set, 8 to 10 minutes. Serve warm.
