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, 1small red onion, thinly sliced, 1 cucumber, preferably hothouse (seedless), thinly sliced (peeled, if desired), 14- to 5-ounce container sprouts (such as alfalfa, radish, broccoli, or a combination), 2 avocados, pitted and thinly sliced

Directions:
1. In a medium bowl, combine the beans, oil, salt, and pepper. Roughly mash the mixture with the back of a fork.

2. Place 8 of the bread slices on a work surface. Divide the mashed beans among them. Top with the onion, cucumber, sprouts, and avocado.

3. 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.

4. Slice each sandwich in half, if desired, and serve.
