Season chicken with taco seasoning and a drizzle of olive oil, season with salt and pepper to taste and cook on the griddle (or stove) until the chicken is fully cooked and slightly crispy, you want a nice char on the outside of the chicken
Once chicken is cooked, dice the chicken into bite sized pieces
Mix the cooked peppers, onions, and diced chicken together on the griddle.
Sprinkle shredded provolone cheese over the mixture and let it melt, stirring occasionally to combine everything.
Place a spoonful of the chicken, pepper, and cheese mixture onto the center of each warm corn tortilla.
Roll the tortilla tightly around the filling and place it seam-side down on the griddle.
Spray with olive oil spray and let the taquitos cook until they are golden brown and crispy on all sides, turning occasionally to ensure even cooking.
Once the taquitos are crispy and cooked to perfection, remove them from the griddle.
Top with a dollop of sour cream and garnish with red pickled onions and sliced jalapenos for an added kick.
