To prepare a meats too expensive vegetarian burgers recipe, you'll need: 2 tbsp. ground cumin 2 tablespoons ground paprika 1 teaspoon kosher salt 1 tablespoon ground black pepper 1 cup chopped romaine lettuce 1/2 cup diced tomatoes 1/4 cup crumbled feta cheese 1 1/2 cups chopped parsley 1 pound frozen green peppers 1 chopped red bell pepper Instructions: Preheat the oven to 450 degrees Fahrenheit (230 degrees Celsius) and grease 2 large frying pans with nonstick cooking spray. Heat the oil over medium-high heat. Add the onion and cook until softened, about 5 minutes. Stir in the garlic and season with salt and pepper. Cook, stirring occasionally, until the onions are translucent, 2 to 3 minutes, then add the tomatoes. Simmer, covered, for 5 to 10 minutes or until tomatoes are heated through. Remove the pan from the heat and stir in 1/4 of the cheese. Spread the remaining cheese on the bottom of each patty. Top each with 1 slice of tomato. Bake, uncovered, in 375 degree F oven until cheese is melted and topping is bubbly, 20 to 25 minutes to an internal temperature of 160 degrees F. Serve warm.
