Spray a microwave safe bowl or cup (8-ounces) with nonstick cooking spray.
Add ham, cheese, onion, bell pepper, potatoes, and egg to the prepped bowl. Mix everything together so it's all coated in the egg.
Put bowl in microwave and cook for 1 minute. Use towel or safe hot plate to remove bowl from microwave to stir.
Put the bowl back in the microwave to cook for another 30-45 seconds, or until everything has been cooked all the way through. The bowl will be VERY hot. Be careful when touching it. Let it cool slightly before serving.
