Step 1

Cook: Warm olive oil in a skillet over medium heat. Add red onion, garlic, thyme, red pepper flakes, and salt. Cook until the onion has softened slightly, but still has its color, 2 to 3 minutes.

Step 2

Combine: Transfer the mixture to a large bowl. Stir in the lemon juice, capers and caper brine. Add beans, bell pepper, parsley, and dill. Toss gently to mix. Taste and add more salt if needed.
