Meanwhile, heat a pan over a high heat with a drizzle of oil. Fry the beef mince and onion for 5 min. Add the garlic and taco seasoning and fry for 2 min. Add the sweet corn and chopped tomatoes. Reduce the heat to low and simmer for 4-5 min or until slightly thickened. Season with salt and pepper to taste (see pro tip).
