Kale and Cashew Pesto With Ciabatta and Heirloom Tomatoes (Serves 4-6) 

This is bruschetta so savoury and satisfying that you could make it a meal.
The pesto can be refrigerated a day in advance; bring to room temperature before using. Assemble the slices shortly before serving.


For the pesto
3/4 cup packed kale leaves (stemmed)
12 basil leaves
1/2 cup raw cashews
1 clove garlic
1/4 cup fresh lemon juice (from 1 large lemon), or more as needed
3 tablespoons olive oil
1/2 to 1 teaspoon kosher salt, or more as needed
Flesh of 1/2 ripe avocado
For the ciabatta
473g small heirloom tomatoes, cut into quarters
6 tablespoons extra-virgin olive oil
6 tablespoons white balsamic vinegar
2 tablespoons honey
1 teaspoon kosher salt
226g to 240g portion of ciabatta (may substitute focaccia bread)
Basil leaves, torn, for garnish
Cracked black pepper, for garnish

For the pesto: 
Combine the kale and basil leaves, cashews, garlic, lemon juice, oil, salt (to taste) and avocado in a food processor; pulse just long enough to create a loose, pesto-like consistency with no large chunks. Taste, and add salt and/or lemon juice, as needed.

For the ciabatta: 
Place the tomatoes in a mixing bowl.
Whisk together the oil, vinegar, honey and salt in a liquid measuring cup, until well incorporated, then pour over the tomatoes and toss gently to coat.
Cut the ciabatta crosswise into 1cm slices, arranging them on a platter. 
Place a good-size dollop of the pesto on top of each one, spreading it with a table knife.
Top with some of the marinated tomatoes and garnish with torn basil leaves and cracked black pepper.
