Smoked marlin shredded and prepared with tomatoes and chiles is a Pacific coast delicacy. This high protein, healthy dish is a fresh, clean eats option ideal for tacos and tostadas.
Heat 1 tbsp olive oil in a large skillet over medium heat until shimmering but not smoking.
Add the chopped onions and minced garlic, sauté for 2-3 minutes until softened and translucent.
Stir in diced roma tomatoes, poblano, and jalapeño; cook over medium-high heat, stirring occasionally, until tomatoes break down and peppers are tender, about 6-8 minutes.
Add the shredded smoked marlin to the skillet; toss well, and cook for 5 minutes, mixing to combine flavors thoroughly while keeping heat at medium to prevent drying out the fish.
Season with salt and black pepper; drizzle in fresh lime juice and toss again. Taste and adjust seasoning if needed. Serve hot inside tacos or on top of crisp tostadas.
