01 - In a medium saucepan, bring the chicken broth to a rolling boil. Add the white rice, stir once, then reduce heat to low. Cover tightly with a lid and simmer for 15–18 minutes until the liquid is fully absorbed and the rice is tender. Remove from heat, fluff gently with a fork, and set aside.
02 - In a large skillet, heat 1 tablespoon of olive oil over medium-high heat until shimmering. Season the thinly sliced steak evenly with ground cumin, smoked paprika, chili powder, salt, and black pepper. Arrange the steak in a single layer in the hot skillet and sear for 2–3 minutes per side until a deep golden-brown crust forms and the meat is just cooked through. Transfer to a plate and tent loosely with foil to rest.
03 - In the same skillet, add the remaining 1 tablespoon of olive oil. Sauté the diced onion and red bell pepper over medium heat for 3 minutes until beginning to soften. Add the minced garlic and jalapeño (if using), and continue cooking for 1–2 minutes until fragrant and the vegetables are tender.
04 - Add the cooked rice to the skillet with the sautéed vegetables. Toss thoroughly to combine and heat through over medium heat for about 2 minutes. Taste and adjust seasoning with additional salt and pepper as needed.
05 - In a small saucepan over low heat, gently warm the queso dip, stirring occasionally. If the consistency is too thick, whisk in the whole milk one tablespoon at a time until the queso reaches a smooth, pourable texture. Remove from heat once warmed through.
06 - Divide the rice and vegetable mixture evenly among four plates. Arrange the seared steak slices over the rice. Drizzle generously with the warm queso sauce. Finish with a sprinkle of fresh chopped cilantro if desired, and serve immediately.
