Preheat the oven to 425°F and line a sheet pan with parchment paper.
In a bowl, drizzle the chicken breast with olive oil and season with cumin, smoked paprika, salt, and pepper.
Place the seasoned chicken on the sheet pan and roast in the oven for 18-20 minutes until the internal temperature reaches 165°F.
While the chicken roasts, prepare the crunchy slaw by combining shredded red cabbage, grated carrot, and chopped fresh cilantro in a mixing bowl.
Squeeze the juice of half a lime over the slaw and toss gently to combine. Season with a pinch of salt and pepper to taste.
Warm the corn tortillas in a dry skillet over medium heat for about 30 seconds on each side.
Once the chicken is done, let it rest for a couple of minutes before slicing it into strips.
Assemble the tacos by layering the roasted chicken strips on the warmed tortillas, adding a generous serving of crunchy slaw, and topping with slices of avocado.
Serve immediately and enjoy your balanced, flavorful taco meal.
