2largesweet potatoespeeled and sliced into rounds 1/4 inch thick
Avocado oilor olive oil
Sea salt and freshly ground black pepper
1poundlean ground beef
8small slices of sharp cheddar cheese*
Sliced red onion
Preheat the oven to 400°F and lightly grease a sheet pan with olive oil. Arrange the sweet potato rounds on the pan in a single layer and season with salt and pepper. Roast for about 20 minutes, or until tender when pierced with a fork.
While the sweet potatoes are roasting, make the burgers. Divide the ground beef into eight equal portions and flatten them into patties. Season them generously with salt and pepper on both sides.
Heat a large heavy skillet over medium-high heat. Add the burgers and cook for 5-7 minutes, until well browned on the bottom, then flip and top with cheese. Cover the pan and cook for 3-8 minutes on the second side, or until the burgers reach your desired doneness. Transfer the burgers to a plate and rest for five minutes.
Finally, place half of the sweet potato rounds first with a bit of lettuce and a patty, followed by sliced onion, avocado, and tomato. Top with the remaining sweet potato rounds. Secure with toothpicks if desired and serve hot.
*You can use the mouth of a small jar or drinking glass to cut out little rounds of cheese from big slices.
Instead of beef, you may use ground chicken or turkey
Any neutral oil will work
