1Heat oven to 400°. Spray 10-inch nonstick skillet with cooking spray; heat over medium heat.
2Pour eggs into skillet. As mixture begins to set at bottom and side, gently lift cooked portions with spatula so that thin, uncooked portion can flow to bottom. Avoid constant stirring. Cook 3 to 4 minutes or until eggs are thickened throughout but still moist.
3Place pizza crust on ungreased cookie sheet. Mix mayonnaise and mustard; spread evenly over crust. Top with eggs, ham, onions, bell pepper and cheese. Bake 10 to 12 minutes or until cheese is melted.
