Step 1

Soak the red onions in ice water for about 5 minutes to soften their flavor. Rinse and drain the black beans. Allow them to drain well while you chop the rest of the vegetables.

Step 2

Finely dice the cucumber to pieces about the same size as the black beans. Finely dice the red onion, and roughly chop the cilantro.

Step 3

In a small bowl, combine the olive oil, vinegar, cumin, garlic powder, salt, and some freshly cracked pepper (about 15 cranks of a pepper mill).

Step 4

Add the black beans, cucumber, red onion, cilantro, and feta to a large bowl. Pour the dressing over top, then fold the ingredients to combine. Allow the salad to sit for 10 minutes to marinate. Serve immediately, or refrigerate up to 4-5 days.
