Bring a medium saucepan of salted water to the boil for the pasta. Finely chop the tomato. Thinly slice the spring onion, keeping the white and green parts separate. Crush or finely chop the garlic. Coarsely grate the cheese.
Step 2 — Cook pasta
Cook the pasta in the pan of boiling water for 10 mins or until al dente. Drain.
Step 3 — Brown beef mince
Meanwhile, heat 1 tsp olive oil in a medium deep frypan over high heat. Cook the beef mince, breaking up the lumps with a spoon, for 3-4 mins until browned. Add the garlic, white part of the spring onion and Tex-Mex seasoning, season with salt and pepper and cook, stirring, for 30 secs or until fragrant.
Step 4 — Simmer sauce
Add the tomato, tomato paste, 125ml (½ cup) water and 1 tsp sugar to the mince mixture. Bring to the boil, then reduce the heat to medium and cook, stirring occasionally, for 5 mins or until slightly thickened. Stir in the pasta. Remove the pan from the heat. Taste, then season with salt and pepper.
Step 5 — Serve up
Divide the taco beef pasta among bowls (see Make it yours) and scatter over the cheese and remaining spring onion. Enjoy!
Step 6 — Make it yours
Fancy a pasta bake instead? Tip the pasta mixture into a baking dish, scatter over the cheese and spring onion, then bake in a 200C oven for 8-10 mins until the cheese is melted.
