Because everything is cooked in the microwave, this Tex-Mex breakfast is ready quickly.
4 servings (serving size: 1 tostada)
Combine first 5 ingredients in a large microwave-safe dish, stirring with a whisk. Microwave at HIGH for 3 minutes; stir. Microwave an additional 1 minute or until done. Arrange 1 tortilla on each of 4 microwave-safe plates; divide egg mixture evenly among the corn tortillas. Layer each serving with 2 tablespoons cheese, 1/4 cup beans, and 1 tablespoon green onions. Microwave each tostada at HIGH for 30 seconds. Top each tostada with 2 tablespoons salsa and 1 tablespoon sour cream. Serve immediately.
