In a large bowl, mix the ground lamb, almond flour, onion, ginger, cilantro, chilis or jalapeno, egg, and salt with your hands to thoroughly combine.
Apply oil to your hands (or use gloves) and form meat into 2-inch round flat patties. Place on a plate and let sit in the fridge for 15 minutes.
Make the aioli: Blend the yolks, garlic and mint in a blender or food processor until well combined. While the blender or processor is running, slowly add in the olive oil in a thin stream. Once incorporated, add in the lemon, salt, and red pepper flakes. Set aside.
Heat ghee or coconut oil in a pan over medium-high heat. Add the patties, being sure not to overcrowd, and saute until cooked through, about 3-4 minutes per side. They should be browned on the outsides.
Serve with a dollop of mint aioli - either on their own, in a lettuce wrap, or with naan bread.
