Follow these simple steps to create your Cheesy Taco Pasta:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain the pasta and set aside.
2. Brown the Meat: In a large skillet, over medium-high heat, add the ground beef or turkey. Cook until browned and fully cooked, breaking it apart with a spoon, about 5-7 minutes.
3. Add Taco Seasoning: Sprinkle the taco seasoning over the cooked meat and stir to coat evenly. Cook for another minute to toast the spices.
4. Combine Ingredients: Stir in the canned diced tomatoes (with juice), chicken broth, and heavy cream (or sour cream) to the meat mixture. Bring to a simmer.
5. Add Pasta: Add the drained pasta to the skillet, tossing to combine everything evenly. Cook for an additional 2-3 minutes to heat through.
6. Add Cheese: Remove the skillet from heat and stir in the shredded cheddar and Monterey Jack cheeses. Mix until the cheese is melted and creamy.
7. Season: Taste and adjust seasoning by adding salt and pepper as needed.
8. Garnish: If desired, garnish with chopped cilantro and sliced jalapeños before serving.
