There is!! Look up either Revolutionary Rolls or their variant (my preferred choice) Oopsie Rolls on the Internet - I have made 1/2 doz whenever I crave a burger or sandwich - and it has perfectly hit the spot! With bacon and egg filling, or cheese and Tomato, or BLT.
Most of the recipes are really simple, 3-4 8ngredients. Our own fluffychix has a great but a bit more complex recipe here: http://fluffychixcook.com/basic-revolution-ary-rolls-low-carb-and-gluten-free/
