There was a good link on a recent discussion of packing lunches for kids but I can't find that post. So here is another link I found by doing a search:

My boys loved Barbecue Cups when they taking lunch to school each day. You can also make them Pizza Cups by using pizza sauce, cooked ground beef or Italian sausage, and mozzarella cheese.
Barbecue Beef Cups
3/4 pound lean ground beef
1/2 cup barbeque sauce
1 tablespoon dried minced onion
1 (12 ounce) package refrigerated biscuit dough
1/3 cup shredded Cheddar cheese
1.Preheat oven to 350 degrees F (175 degrees C). Grease the cups of a muffin pan.
2.In a large heavy skillet over medium heat, cook beef until evenly brown. Drain excess fat. Stir in barbeque sauce and dried onion. Simmer for a few minutes over low heat.
3.Flatten each biscuit, and press into cups of the prepared muffin pan. Make sure the dough comes to the top of the pan. Spoon a portion of the meat mixture into each dough cup.
4.Bake in preheated oven for 12 minutes. Sprinkle with cheese, and bake for 3 more minutes.
Look on the Pillsbury web site for more recipes using canned biscuits and pizza dough to make little hand held pies or buns, just the right size for little folks.
