Drain the canned tuna thoroughly and place it in a large mixing bowl. Add the egg, rice crumbs, minced garlic, mayonnaise, chopped mini sweet peppers, green onion, Sriracha, and dill pickle relish. Mix everything well until all the ingredients are evenly combined.

Using your hands, take portions of the tuna mixture and shape them into cakes about 2-3 inches wide. Refrigerate for about 30 minutes to enhance their texture.

Choose between cooking in a skillet or an air fryer. For skillet, heat oil over medium heat. For air fryer, preheat to 360°F and spray the basket with oil.

For skillet, place patties in heated oil and cook for about 4-5 minutes on each side. For air fryer, arrange cakes in a single layer, brush with olive oil, and air fry for 5 minutes, then flip and cook for another 3-4 minutes.

Remove the cakes from heat and serve immediately alongside lime wedges.
