This is so easy it's almost embarrassing. My mom used to make these for my brother and I when we were kids. I like to make them for a quick lunch for IT Guy and myself. I usually just go the cheese route, but adding toppings makes them extra yummy. It's a great little item that older kids can make for themselves. Just keep the ingredients on hand and they've got a quick after school snack!
1 loaf sliced french bread
1 jar pizza sauce
Pepperoni, cooked sausage, olives, etc (optional)
Preheat oven to 375 degrees.
Lay your bread onto a couple of cookie sheets.
Spoon the pizza sauce over the bread then sprinkle with cheese.
Bake for about 15 minutes until bread is toasted on the bottom and toppings are hot. Broil for a couple of minutes, if desired.
