Bring a medium pot of salted water to a boil. Wash and dry produce.

Core, deseed, and finely dice bell pepper. Drain corn and pat dry with paper towels. Trim and thinly slice scallions, separating whites from greens. Mince half the jalapeño (whole jalapeño for 4 servings), removing ribs and seeds for less heat.

Once water is boiling, add penne to pot. Cook, stirring occasionally, until al dente, 9-11 minutes. Reserve ½ cup pasta cooking water (1 cup for 4 servings), then drain.

Open package of chicken* and drain off any excess liquid. Heat a drizzle of oil in a large pan over medium-high heat. Add chicken in a single layer; season with salt and pepper. Cook, stirring occasionally, until browned and cooked through, 4-6 minutes. Turn off heat; transfer to a plate. Wipe out pan.

While pasta cooks, heat a drizzle of oil in a large pan over medium heat. Add bell pepper and season with a pinch of salt and pepper. Cook, stirring occasionally, until tender, 5-7 minutes. TIP: If bell pepper starts to char, add a few splashes of water.

Use pan used for chicken here.

Add a drizzle of oil and corn to pan with the bell pepper. Cook until corn is lightly charred, 4-6 minutes.

Add scallion whites, garlic powder, half the Fajita Spice Blend (all for 4 servings), and minced jalapeño to taste. Cook, stirring occasionally, until fragrant, 2-3 minutes.

Remove from heat. Transfer ¼ of the veggie mixture to a plate; reserve for serving.

Return pan with remaining veggies to stovetop over low heat. Stir in drained penne, cream sauce base, cream cheese, half the pepper jack, half the scallion greens, and ¼ cup reserved pasta cooking water (½ cup for 4 servings). Cook, stirring, until cream cheese is just melted and pasta is coated in a creamy sauce. (For 4, if pan is too small, carefully transfer everything to empty pot used for pasta.)

Remove from heat; stir in 1 TBSP butter (2 TBSP for 4) until melted. Taste and season generously with salt and pepper. TIP: If needed, stir in more reserved cooking water a splash at a time.

Stir in chicken along with drained penne.

Divide pasta between bowls. Top with reserved veggies and remaining pepper jack. Garnish with remaining scallion greens and serve.
