Combine beans, tomato, and mustard for a delicious cucumber salad. A tangy, refreshingly cool meal or side perfect for the summer.
Add cooked beans, chopped tomato, and chopped cucumber to a bowl. Top with mustard and mix well to combine.
Optional ingredients (avocado, red cabbage, cilantro) can be mixed in too. Then enjoy!
Leftovers will last covered in the refrigerator up to 3 days, though best when fresh.
