Arrange English muffin quarters in a single layer in a greased 3-quart rectangular baking dish. Set aside.
In a large bowl, beat together eggs, milk, chile peppers, salt, and black pepper with a rotary beater or whisk until well mixed. Pour egg mixture over muffin quarters; sprinkle with ham, green onions, and olives. Top with roasted sweet pepper, provolone cheese, and cheddar cheese.
Preheat oven to 350 degrees F. Bake, uncovered, about 35 minutes or until a knife inserted near the center comes out clean. Let stand for 10 minutes before serving.
