Take a large bowl and add ground beef, 1 tbsp. Low FODMAP Certified Spice Mix (BBQ Seasoning Rub) and 0.5 tsp. Kosher salt. Mix the ingredients until well-combined. Divide the patty mixture equally and make patties (2 per each person). Cover the patties in a plastic wrap; place them into the refrigerator for about 15 minutes.
Take a large pan and lightly grease the pan with the cooking spray. Heat the prepared pan over medium-high heat. Fry the patties in the pan for about 7 minutes per each side, or until thoroughly cooked.
Meanwhile, cut thin slices of the cucumber and tomatoes to prepare the ingredients for the salad.
Toast the gluten-free buns, if desired. To assemble the burger, place the patty, salad and cheese slice. Drizzle with mayonnaise, if desired. Serve and enjoy!
Notes
You can even freeze the beef patties for up to a month and defrost in the refrigerator for 10-12 hours before cooking.
