VEGGIES: Heat oil in a large pot over high heat. Add the onion & pepper, cooking for 3-5 minutes or until onion is translucent. Push veggies to edges of the pan.
BEEF: Add beef in center of pan. Allow it to sear for about 1 min per side, then break it apart with a wooden spoon as it cooks. Continue until the beef is mostly browned, with some pink remaining.
SEASONINGS: Mix in the garlic, tomato paste, & taco seasoning. Season with salt and pepper; I add 1/4 tsp salt & 3/4 tsp pepper. (See Note 4). Stir and continue to cook until beef is fully browned through.
BRING TO BOIL: Add tomatoes, enchilada sauce, & chicken broth to the pot. Bring the mixture to a full boil.
SPAGHETTI: Break spaghetti in half and submerge it in the liquid. Cook for 10-12 minutes, stirring often and scraping the bottom of the pot to prevent pasta sticking. About 8-10 minutes in, reduce the heat to medium to avoid evaporating too much liquid before the pasta is done. (Note 5 for troubleshooting)
ADD CHEESE: Once the pasta is al dente (slightly firmer than desired), remove the pot from heat. The dish should be quite saucy. Using tongs, toss the pasta for about a minute until the sauce thickens and pasta is perfectly tender. Allow the mixture to cool slightly, then gradually add the cheddar cheese, 1/4 cup at a time, tossing until fully incorporated to avoid clumping.
ENJOY: Serve immediately and enjoy!

Notes
Note 1: For the most possible flavor, make your own (otherwise we recommend a good brand for the most flavor).
1 teaspoon each paprika,cumin, garlic powder, onion powder
1/2 teaspoon oregano
(Use these seasonings in place of the taco seasoning packet.)Note 2: Various brands of enchilada sauce can vary quite a bit in heat. We like Old El Paso mild red enchilada sauce in this recipe.Note 3: Liquid is depending on 12 oz. regular spaghetti being used. Use a food scale (if possible) to be precise here!Note 4: If you are using a packet, they're typically a lot more salty, so adjust salt/pepper to taste.Note 5: Troubleshooting:
Sauce Soaked Up & Pasta Not Tender? Lower the heat slightly. Add extra broth if needed.
