In a large mixing bowl, combine the shredded chicken, queso fresco, black beans, cumin, garlic powder, onion powder, and cilantro. Season with salt and pepper to taste, and mix until well combined.
Heat the corn tortillas in a dry skillet over medium heat for about 30 seconds on each side to become pliable.
Take one tortilla, add about 2-3 tablespoons of the chicken mixture to the center, and roll it tightly, tucking in the sides as you go to form a sealed taquito.
Repeat the process with the remaining tortillas and filling.
In a large frying pan, heat vegetable oil over medium-high heat. Once the oil is hot, carefully add the taquitos seam-side down, frying in batches to avoid overcrowding the pan.
Fry for about 2-3 minutes per side, or until they are golden brown and crispy. Remove with a slotted spoon and place on a paper towel-lined plate to drain excess oil.
Serve hot, garnished with optional toppings like guacamole, salsa, and sour cream.
Notes
Arrange the taquitos on a platter with dipping bowls of guacamole and salsa in the center. Garnish with additional cilantro leaves for a pop of color.
