Grilled prawns, bacon and bananas, avocado and chilli mayonnaise

—
1. Peel the prawns (shrimp) but keep the tails on. (You can freeze the shells for making a delicious bisque at some later point.) Run a small sharp knife along the ‘spine’ of the tail and remove and discard the digestive tract.
2. Peel the banana and slice on an angle 5mm (¼ in.) thick. Gently toss or brush both the prawns (shrimp) and the banana with the oil.
3. Rinse the shallot rings in cold water for a minute, separating them, then drain. Mix with the lime zest and 1 teaspoon of the juice.
4. Mix the mayonnaise with the remaining 1 teaspoon of lime juice and the chilli sauce to taste. Check for seasoning, adding salt if needed.
5. You can cook this either under the grill (broiler), in a frying pan (skillet) or on a barbecue. Heat the grill (broiler) or pan (skillet) medium–high and cook the bacon until crisp and bubbling with fatty juices. Remove from the heat and keep warm nearby. Cook the prawns (shrimp) for no more than 60 seconds on each side, depending on their size. Sit the prawns (shrimp) with the bacon and keep warm. Cook the banana on both sides until beginning to caramelize. It’ll be quite soft when you turn it over, so treat it gently. Remove from the heat.
6. Toast the bread. Peel the avocado, remove the stone (pit), scoop out the flesh and cut into wedges.
7. To serve, gently mix the prawns (shrimp), bacon, banana, shallots, avocado and spinach together, then pile on top of the toast. Serve with the chilli mayonnaise.
