Method

1. Preheat the grill
2. Mash the avocado flesh in a bowl with a fork. Stir in the cheese and season with a little black pepper (it’s unlikely that you’ll need any salt)
3. Toast the slices of bread on one side only, turn them over and spread the avocado mixture thickly on top. Return to the grill and toast until the cheese starts to brown. Serve at once

Cook’s tip: The avocado mixture makes an excellent sandwich filling with sliced tomatoes, crispy bacon and salad leaves – or simply use it on its own!
