Big things often come in small packages. These sliders pack a flavorful punch that is sure to be enjoyed by all. This recipe can be written dozens of ways, depending on your various condiment preferences. The best thing about these paleo-friendly offerings is that you don't have a doughy soft bun to get in the way of your fresh lettuce and tomatoes.
Sliders can be a great appetizer for a big crowd or a meal for a smaller crew. This is also a really fun recipe to get kids involved in the process. Who doesn’t remember getting to make burgers as a kid?
1–1½ pounds (500-750 g) ground beef
1 large egg
1 small onion, finely chopped
1 cup (100 g) mushrooms, finely chopped
1 teaspoon (5 ml) black pepper
½ teaspoon garlic salt
1 each: yellow, red, green bell pepper
1 small onion, sliced
3 small tomatoes, sliced
1 head iceberg lettuce
6–8 medium portobello mushrooms
- Preheat your grill to medium-high heat. Be sure you have a clean grate and wipe it down with a little oil when hot.
- In a large bowl, mix ground meat, egg, chopped onion and mushrooms. Sprinkle in black pepper and garlic salt as you’re mixing the meat.
- Form small burgers with hands (no need for a fancy slider mold here). The burgers will be about 2 inches in diameter.
- Slice all three peppers down the sides to form large flat pieces (think like you’re cutting the walls off a house).
- Slice other onion and tomatoes thinly (about 1/8 inch). Pull lettuce apart into individual leaves. Try to keep them whole (as large as possible).
- Grill burgers 3-5 minutes per side, depending upon your desired doneness. Grill peppers and mushrooms 2-3 minutes per side, or until cooked through.
- Stack burgers between peppers or mushrooms and wrap with lettuce. Add the onion and tomato slices if you’re so inclined.
Variations—If you’d like, slice the tomatoes a bit thicker to use as bun—just know they’ll be pretty juicy.
—With sliders/burgers you can use almost any ground meat you want. We like to occasionally use ground turkey or ground venison.
—We always try to have a batch of our homemade Paleo Mayo, Cave Ketchup (recipe here), or Chipotle Dipping Sauce (recipe here) ready to serve on top of these.

Pro Tips
- Mix the ground meat with the egg, onion, and mushrooms gently - overworking the meat makes the sliders dense.
- Cut the pepper walls off in large flat slabs so they hold up as buns; think of cutting the walls off a house.
- Wipe the hot grill grate with a little oil before the meat goes on - the small patties stick easily.
- Keep the lettuce leaves whole and large; torn leaves cannot hold the stack together.
