I don't know if it counts as homemade or few ingredients but one of my favorites is take about four or five inches of French bread. Split it in half like you are going to make a sandwich.

Find something along the line of ham or pepperoni in the fridge and add a small bit to the top. If I have onion I'll add that too. Cover with a couple slices of cheese and microwave for about 1:15. Boom you got a quick pizza snack.
