Use a basting brush to brush 1 tablespoon olive oil on the crusts, then sprinkle them with garlic powder, to taste.
Bake pizza crusts according to package directions, or until warmed through and lightly browned on edges.

Add chicken pieces and pepperoni hearts, evenly spaced, to each crust.
Bake heart pizzas according to crust package directions, or until they are heated through and the cheese is melted and bubbling.
