Combine the ricotta and garlic with a large pinch of salt and pepper in a bowl. Put the vegetables and pasta sauce in a large heatproof mug or ramekin. Cover and microwave on high for 3 mins until tender. Season. Stir in half the basil.

Spoon two-thirds of the veg mixture from the mug or ramekin into a bowl, then start to layer up the lasagne in the mug. Top the veg mix in the base of the mug with half a lasagne sheet, then spoon over another third of the veg mix and top with another halved pasta sheet and half of the ricotta. Repeat, finishing with the ricotta. Sprinkle over the mozzarella. Microwave on high for 2 mins. Scatter over the remaining basil and some black pepper before serving.
