For a refreshing and light veggie sandwich, make an avocado and cucumber sandwich using your food processor. Process ripe avocados with lemon juice, salt, and pepper until smooth and creamy. Spread the avocado mixture on whole grain bread and top it with thinly sliced cucumbers, sprouts, and a sprinkle of sea salt. This sandwich is perfect for a quick and healthy lunch option, and the creamy avocado adds a satisfying richness to every bite.
