Preheat your oven to 400 F. If grilling, aim for medium heat.

Brown the ground beef in a skillet. Drain extra grease if needed. Stir in taco seasoning and a splash of water, then simmer for a minute or two until it looks saucy.

In a bowl, mix the cooked beef with rice, corn, beans if using, and salsa. Taste it and adjust with salt, pepper, or extra salsa.

Tear off 4 large pieces of foil. Spray lightly with cooking spray or rub with a tiny bit of oil.

Scoop the taco rice mixture into the center of each foil piece. Top each with a generous handful of cheese.

Fold the foil into packets. Bring the long sides up, fold them together, then fold in the ends so it is sealed.

Bake for 12 to 15 minutes, just until hot and the cheese is melted. On the grill, it is usually about 10 to 12 minutes, flipping once carefully.

Let them sit for 2 minutes before opening. Open carefully and top with your desired toppings.
