Prep the marinade: In a bowl, whisk lime juice, orange juice, olive oil, garlic, chili powder, cumin, smoked paprika, oregano, salt, and pepper until combined.
Marinate the chicken: Add the chicken thighs, turning to coat well. Cover and refrigerate for at least 30 minutes and up to 6 hours. Tip: The citrus tenderizes quickly—no need to go overnight.
Heat the pan or grill: Use a cast-iron skillet or grill over medium-high heat.
Let it get hot before adding the chicken for a good sear.
Cook the chicken: Shake off excess marinade and cook 4–6 minutes per side, depending on thickness, until nicely charred and cooked through. Internal temperature should reach 165°F (74°C).
Rest and chop: Let the chicken rest 5 minutes, then chop into small, bite-size pieces. This keeps it juicy and perfect for small tortillas.
Warm the tortillas: In a dry skillet or directly over a low gas flame, warm tortillas 20–30 seconds per side until pliable and lightly blistered.
Keep them wrapped in a clean towel.
Assemble: Fill each tortilla with chopped chicken. Top with onion, cilantro, a squeeze of lime, and salsa. Add avocado, cheese, or radishes if you like.
Serve immediately: Street tacos shine when hot, fresh, and simple.
Put limes and extra salsa on the table.
