Make some tiny roasties - cut up your tatties, spritz them with some spray oil and put them in the oven for about twenty minutes until they're nice and crisp. Alternatively, use an Actifry.
In a pan, soften the onions in a slick of olive oil. Once softened, add the tomatoes and garlic. Cook until softened.
Add the prawns to the pan with a pinch of salt and black pepper. Cook until the prawns are pink on the outside and opaque in the middle.
To serve, place a few roasties in the middle of each plate. Top with rocket, tomato and onion mixture, and prawns.
Drizzle with pesto before serving.
