To a large bowl add the drained tuna, egg, cilantro, onion, yogurt or mayo, almond flour, jalapeno, lemon or lime juice, garlic powder, cumin, and a generous sprinkle of salt and pepper. Mix with a fork until fully combined. Shape mixture into 6-8 patties.
Heat oil in a skillet over medium heat; fry patties until golden brown, about 5 minutes per side. Serve with a side of avocado salad, in a sandwich, on a bed of greens or with a side of veggies. Drizzle with sriracha aioli if desired.
To make cilantro aioli: whisk Greek yogurt or mayo, sriracha, and lime juice until combined.
