Season the chicken with salt, pepper, and paprika. Give it a quick toss so every piece feels fancy.
Heat olive oil in a skillet over medium-high heat. Add chicken and cook until lightly browned and cooked through. Remove and set aside.
In the same pan, add onion and bell pepper. Sauté until they’re tender with a little color, about 4–5 minutes. Add garlic and cook 30 seconds more.
Pour in the chicken broth, scraping up any tasty browned bits from the bottom. Let it simmer for a minute to reduce slightly.
Return the chicken to the pan. Sprinkle shredded pepper jack cheese over the top and cover just long enough for the cheese to melt (1–2 minutes).
Stir gently to combine everything into a saucy, cheesy nest. Taste and adjust salt and pepper if needed. Garnish with cilantro or parsley.
