Slow-cooker vegetable lasagne

Ingredients
1 tbsp rapeseed oil
2 onions, sliced
2 large garlic cloves, chopped
2 large courgettes, diced (400g)
1 red and 1 yellow pepper, deseeded and roughly sliced
400g can chopped tomatoes
2 tbsp tomato purée
2 tsp vegetable bouillon
15g fresh basil, chopped plus a few leaves
1 large aubergine, sliced across length or width for maximum surface area
6 wholewheat lasagne sheets (105g)
125g vegetarian buffalo mozzarella, chopped

Method
STEP 1
Heat 1 tbsp rapeseed oil in a large non-stick pan and fry 2 sliced onions and 2 chopped large garlic cloves for 5 mins, stirring frequently until softened.

STEP 2
Tip in 2 diced large courgettes, 1 red and 1 yellow pepper, both roughly sliced, and 400g chopped tomatoes with 2 tbsp tomato purée, 2 tsp vegetable bouillon and 15g chopped basil.

STEP 3
Stir well, cover and cook for 5 mins. Don't be tempted to add more liquid as plenty of moisture will come from the vegetables once they start cooking.

STEP 4
Slice 1 large aubergine. Lay half the slices of aubergine in the base of the slow cooker and top with 3 sheets of lasagne.

STEP 5
Add a third of the ratatouille mixture, then the remaining aubergine slices, 3 more lasagne sheets, then the remaining ratatouille mixture.

STEP 6
Cover and cook on High for 2½ - 3 hours until the pasta and vegetables are tender. Turn off the machine.

STEP 7
Scatter 125g vegetarian buffalo mozzarella over the vegetables then cover and leave for 10 mins to settle and melt the cheese.

STEP 8
Scatter with extra basil and serve with a handful of rocket.
