Step 1

To make your lasagne, set the grill to high. Slice the aubergines thickly into rings (getting 12 slices from each). Brush both sides with a little oil and pack them on a baking sheet. Grill for 4-5 mins on each side, until browned. Set aside, then oil and grill the onion slices until just browned.

Step 2

Meanwhile, cook the lasagne sheets in a pan of boiling water for about 4 mins. Drain well and set aside.

Step 3

Set the oven to 200°C/400°F/Gas Mark Line a baking sheet with baking parchment. Put 4 pieces of lasagne on it, brush them with oil, then pile on 2-3 slices of aubergine, a few onion rings, a couple of slices of mozzarella, seasoning and ½ a tbsp of pesto. Brush the other pieces of lasagne with oil, arrange at angles on top and repeat the aubergine, onion, cheese and pesto layering.

Step 4

Bake for 10-15 mins, until the cheese is melted and browning. Serve on hot plates, drizzle with extra olive oil and garnish with basil.
