Step 1

Heat grill to high. Put the bacon and cherry tomatoes, cut side up, on a grill rack and grill for 10 mins, turning the bacon halfway through, until crisp. Meanwhile, roughly mash the avocado with a fork and stir in the lime juice, chilli flakes, some salt, if you like, and pepper.

Step 2

Toast the bread until golden and spoon on the mashed avocado. Top with the tomatoes and bacon, then serve.
