Our mantra for summer cooking: Keep it simple—and take it outside. That’s where these fuss-free flatbread recipes come in. (Each serves four people as an entree, or you can slice ’em into premeal nibbles.) Start with easy homemade dough that puffs up quickly on the grill—or grab store-bought naan—and layer on ripe fruits and vegetables, favorite cheeses, and bright sauces. Return the quasi pizzas to the grates, warm through, and you’re done. Isn’t summer the best?
