No pasta lasagne

There's an argument that this is no longer lasagne as it has no pasta and doesn't have the traditional bechemal sauce but for anyone who can't eat pasta and prefers a healthier option, it tastes fab! It's really easy to make and can be frozen

500g minced beef
1 red onion, peeled and chopped
3 cloves garlic, crushed
1/2 butternut squash, peeled and cubed
4 carrots, peeled and finely sliced
150g mushrooms, chopped
1/2 leek (use the other half as pasta sheets- do not chop)
2 tins tomatoes
4 tbsp tomato puree
Fresh basil
Fresh parsley
Freshly ground black pepper

For the sauce

350g cottage cheese
250g natural yoghurt
2 eggs

1. Peel and slice all the vegetables then fry the onion, garlic and mince until browned. Add the remaining vegetables ensuring you keep back half the leek to use later. Leave to simmer for 30 minutes then season
2. Preheat the oven to 180OC. Slice the leek in half lengthways. Blend the cottage cheese, yoghurt and eggs together then season with black pepper.
3. Once the lasagne is cooked, layer the lasagne mix and leeks. For the final layer, use the cheese and yoghurt mix. Then place in the oven to cook for 35-40 minutes until the topping is golden brown.
