1Prepare caramelized onions by cooking diced onions until water evaporates and they start browning. Deglaze with beef bone broth in small amounts, stirring and boiling until the liquid reduces completely. Repeat until all broth is reduced. Add soy sauce for flavor and color.
2In the same pan, add extra lean ground beef and seasonings (salt, onion powder, garlic powder, black pepper, oregano, cumin).
3Add diced tomatoes and half the batch of caramelized onions.
4Add 2% and fat-free cheddar cheese, mix well, and let the mixture cool in the fridge to thicken.
5For the low-calorie burger sauce, combine light mayo, plain Greek yogurt, sugar-free ketchup, sweet relish, half of the remaining caramelized onions, garlic, pepper, and salt. Mix until smooth.
6Assemble the burritos by spreading the burger sauce on a tortilla, adding the meat mixture, and rolling it up. Repeat this 14 times. Store frozen.
