My Mom used to make these when I was little - and now, as an adult, I've learned that it's fun to cook these when babysitting the neices, as they can "take orders" and make customized pizzas for others and themselves.
Note: On the pizza toppings, when there are children helping, I prepare all the toppings in advance and have them set out in separate bowls to make it easy for them to customize their own pizza to their liking.
Roll out biscuits one at a time in flour to form thin round individual pizza crusts. Dust excess flour off and place crust on a cookie sheet. (You can usually fit about 4 of these per cookie sheet.)
Add pizza sauce to each pizza. Add whichever toppings you prefer. Top with mozarella cheese.
Bake at 375 for about 15 minutes or until cheese is melted and crust edges are sligtly brown.
