Fire pit and a Dutch oven is one possibility. Google campfire bread baking.
Making pizzas beneath the broiler and flat breads in pans is an alternative choice.
If you’ve got a BBQ with a lid, a Dutch oven may pass in there. Turn at the burners on one aspect and put the Dutch oven at the different aspect so you aren’t getting direct warmth. Heck, may paintings without a Dutch oven if it has a thermometer within the lid.
