Combine tuna, eggs, almond flour, plain yogurt, lemon juice, green onion, salt, and ground black pepper in a large bowl.
Add the finely chopped red bell pepper and cilantro to the mixture, stirring until well combined.
Heat olive oil in a non-stick skillet over medium-high heat.
Form the tuna mixture into patties, about the size of your palm.
Fry the patties in the skillet for about 3 minutes per side, or until golden brown.
Remove from the skillet and let them drain on a paper towel-lined plate.
Garnish with cilantro leaves and serve with a side sauce made from avocado, yogurt, and lime juice.
Variations & Tips
For a gluten-free option, make sure your almond flour is certified gluten-free. If you prefer a milder flavor, you can reduce the amount of cilantro or omit it altogether. For an extra kick, add a pinch of cayenne pepper or a dash of hot sauce to the mixture. You can also swap the red bell pepper for roasted red peppers for a slightly different flavor profile. If you’re not a fan of tuna, try using canned salmon instead.
