Morning stew-filled tacos from market vendors offer a variety of homestyle fillings. This protein-rich, family-friendly dish is a fresh, satisfying way to start the day in Mexico.
Season the chicken breast with salt, pepper, cumin, and smoked paprika. Heat 1 tbsp olive oil in a skillet over medium-high and sear chicken 2–3 minutes per side until lightly browned.
Reduce heat to medium, cover, and cook chicken for 10 minutes with 1/3 cup water until just cooked through and juices run clear. Remove chicken and shred with two forks.
In the same skillet, add remaining olive oil and sauté diced onion and minced garlic for 3 minutes until translucent without browning.
Stir in chopped roma tomatoes and pinto beans. Simmer over medium heat 8–10 minutes, mashing some beans for a creamy, stew-like consistency.
Return shredded chicken to the skillet, fold in half the chopped cilantro, check seasoning, and simmer for 3 more minutes. Keep filling warm for assembly.
Heat corn tortillas on a dry skillet over medium-high heat, 20 seconds per side, to make them soft and pliable.
Assemble tacos by spooning generous filling into each tortilla and topping with the remaining fresh cilantro and diced onion. Serve immediately.
