Lay bagel halves face up on a cutting board or work area.

Spread a thin layer of spaghetti sauce on the top of each half.

Cover the bagel with mozzarella cheese. Use shredded or sliced cheese - whichever you have on hand. Both melt easily.

Add desired toppings (pepperoni, veggies, extra cheese, etc).

Place on the baking tray that comes with your toaster oven. (If you don't have a toaster oven, these can be made just as easily on a cookie sheet in your regular oven.)

Heat at 350 degrees for about 5 minutes or until the cheese melts and just starts to bubble.

Careful - bagels will be hot for little hands and mouths!
