First, make the white bean pate. Add the beans and garlic to a bowl, then add the herbs, oil, chilli, salt and pepper and mash, leaving some whole beans for texture. You can add extra chilli for more kick.
Spread two slices of bread with mayo and top with spinach and cucumber slices.
Now add a generous layer of the bean pate (there's enough for 2 sandwiches), top with sundried tomatoes and slices of tomato.
Spread the second 2 slices of bread with mango chutney and top each stacked sandwich.
Cut in half and serve.
