In a bowl add the ground chicken, almond flour, slivered sun-dried tomatoes, egg, minced onion, chopped basil, salt and pepper. I like to wear gloves and mix with my hands. Form into four patties. Note: if the sun-dried tomatoes are not soft, soak them for 5 minutes in warm water before slicing.
Make the sun-dried tomato sauce: by adding the sun-dried tomatoes, mayonnaise, garlic cloves, fresh basil leaves, olive oil, salt, and cayenne pepper to a high speed blender till smooth. Refrigerate while cooking the burgers if you want a thicker sauce. It can be warmed up in a saucepan on your grill or stove-top if you like.
Heat your grill: add some oil so the burgers do not stick. Cook the burgers 5-7 minutes per side or until they reach 165˚ on a meat thermometer. They can also be cooked inside in a frying pan by heating the oil and cooking for the same amount of time.
Serve it with red onion slices: optional but delicious!
Enjoy!
