Preheat oven to 350°.In a large bowl, beat eggs.
Add onion, bell pepper, cajun seasoning, garlic powder.
Stir in ham and cheese.Spoon by 1/3 cupfuls into muffin cups coated with cooking spray.Bake 20 minutes then remove from oven and top with reserved cheddar cheese, the cook 5 more minutes or until a knife inserted near the center comes out clean.NOTES: I recommend lining the muffin pan with cupcake liners sprayed with cooking spray for easier removal!
