Combine 1lb ground beef, 1 egg, 1/3 cup chopped onions, 3 tsp old bay seasoning and 1/3 cup almond flour. Pan fry or grill until cooked through.
Slice and sauté red/yellow/orange pepper, red onion, and mushrooms with old bay seasoning and garlic.
Dug in a little before taking the picture :)
Take one piece of lettuce and layer burger and vegetables. I added avocado on top
It was so flavorful no condiments needed!
