Maybe a Mexican rice concoction -- rice, black beans, tomato sauce, onions, green peppers, ground meat, corn, spices, cheese -- my recipe is to start throwing stuff in a bowl til it looks right.
Corn tortillas are usually gluten free if that helps with ideas, just read the label. So is rice.
I know corn tortilla and rice are gf but I need recipes or ideas for a potluck!
Could you do tortilla rolls (typically spread with cream cheese or soft cheese then stuffed with lunch meat and/or veggies) with corn instead of flour tortillas?
Another idea would be to throw a ham in the oven or crockpot & bring that over. Those are good room temp or cold.
