Begin by heating the olive oil in a large skillet over medium heat. Once hot, add the cubed chicken breasts. Cook for about 5-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through.
Sprinkle the taco seasoning over the cooked chicken. Add 1 tablespoon of water to help distribute the seasoning evenly. Stir well to coat the chicken in the spices.
Pour in the half and half and stir to combine. Let it simmer for a few minutes, allowing the sauce to thicken slightly.
Add the melted Queso Blanco and salsa to the skillet. Stir until everything is well combined and heated through. The sauce should be creamy and flavorful.
While the chicken is simmering, prepare the instant white rice according to package instructions. This usually takes just a few minutes, making it a quick side!
Stir in the chopped cilantro, green chiles, and pico de gallo. Mix until everything is well combined. Let it cook for an additional 2-3 minutes to heat through.
Sprinkle the shredded Mexican blend cheese on top of the skillet mixture. Cover the skillet with a lid and let it sit for a few minutes until the cheese melts.
Serve the Skillet Chicken con Queso over a bed of fluffy white rice. Garnish with additional cilantro if desired. Dig in and enjoy the creamy, cheesy goodness!
