Notes:

Ingredients:
2 15-ounce cans white beans, rinsed and drained
2 tablespoons extra-virgin olive oil
1/2 teaspoon kosher salt
1/4 teaspoon black pepper
12 slices multigrain bread
1 small red onion, thinly sliced
1 cucumber, preferably hothouse (seedless), thinly sliced (peeled, if desired)
1 4- to 5-ounce container sprouts (such as alfalfa, radish, broccoli, or a combination)
2 avocados, pitted and thinly sliced

Directions:
In a medium bowl, combine the beans, oil, salt, and pepper. Roughly mash the mixture with the back of a fork.
Place 8 of the bread slices on a work surface. Divide the mashed beans among them. Top with the onion, cucumber, sprouts, and avocado.
Stack the open-faced sandwiches on top of one another, avocado-side up, to make 4 double-decker sandwiches. Top with the remaining 4 slices of bread.
Slice each sandwich in half, if desired, and serve.
