Cook the pasta in salted water according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add the chicken strips, season with salt and pepper, and sauté until browned and cooked through.
Add the sliced onion, red, and green peppers to the skillet with the cooked chicken. Cook for 4-5 minutes until the vegetables soften.
Stir in the minced garlic, chili powder, cumin, and smoked paprika. Cook for another minute until fragrant.
Pour in the chicken broth, scraping any browned bits off the bottom of the skillet.
Mix in the heavy cream and bring the mixture to a simmer.
Add the cooked pasta to the skillet, stirring gently to combine everything uniformly.
Let the pasta sit for a couple of minutes off heat for the sauce to thicken further, then serve with cilantro.
