This is a lazy take on cottage pie. Instead of using the oven, we cook the mince on the hob and simply serve with the mashed sweet potato for a quick and easy alternative.
Over a medium heat, pour the vegetable oil to a large frying pan. When hot, add the onion and fry until translucent.
Add the plant-based mince and diced carrot and fry until the mince is cooked through, stirring often.
Cook the sweet potato. To microwave, place the sweet potato cubes in a microwave-safe container with a little salt and 2 tbsp water. Cover and microwave on high until tender, about 4 minutes. Drain and set aside. To cook on the hob, drop the sweet potato cubes into a pan of salted boiling water and cook until tender, about 8 minutes. Drain and set aside.
Meanwhile, add the tomato purée, vegetable gravy granules, and mixed herbs to the mince. Stir well to incorporate, then add water a little at a time until the mince mixture reaches the desired consistency. Taste and season.
Add the plant-butter to the sweet potato and mash together until smooth. Taste and season.
Divide the mince between two bowls and spoon the mashed sweet potato on top. Serve alongside steamed green vegetables.
