Pre-heat to 425 degrees, and roll out to dough to roughly a 8 by 10 rectangle. Place dough on a parchment lined baking sheet.
Combine the chickpeas, onions and barbeque sauce in a bowl. Toss until chickpeas are coated. Spread the mixture evenly on the dough and top with shredded cheese.
Bake for 15 minutes, then top with chopped basil before serving.
