How to Make It
Preheat the broiler. On a baking sheet, brush both sides of the bread with 2 tablespoons of the oil. Broil the bread, turning once, until the edges are deep golden, 4 minutes. Rub the garlic clove over the top of the toasted bread.
In a medium skillet, heat the remaining 2 teaspoons of oil. Add the sausage and cook over moderate heat, breaking it up, until browned and cooked through, 4 minutes. Add the peppers and crushed red pepper and cook until heated through, 1 minute.
Spread each piece of bread with some of the ricotta. Season the ricotta with salt and pepper and top with the sausage mixture. Sprinkle with the basil and serve.
