Shred brussels sprouts using a mandolin or slice thinly. Lay on a baking sheet and drizzle with 2 tablespoons olive oil. Season with garlic powder and sea salt, massage into sprouts, and spread evenly.
Spread white beans and chickpeas on another baking sheet, cover with 2 tablespoons olive oil, and season with paprika, oregano, and cumin. Rub seasoning and oil into beans.
Roast brussels sprouts and beans in the oven at 400°F for 15-20 minutes until crispy at the edges.
Dice red onion, chop Kalamata olives, core and dice bell pepper, mince dill and parsley, and add to a large salad bowl with the roasted beans and brussels sprouts.
Add ¼ cup olive oil, lemon juice, oregano, and red wine vinegar. Toss salad until all dressing is coated.
Crumble feta cheese and toss gently.
Serve and enjoy.
