PREPARATION SUGGESTIONS
ROASTED AND PEELED
Roast whole at 450°F (230°C) until skin blisters (25–30 min). Steam in a covered bowl, peel, slice, and finish with olive oil and salt.
RAW IN SALADS
Slice into strips for crunch and sweetness; pair with feta, olives, and a simple vinaigrette.
STUFFED PEPPERS
Fill with Italian sausage, riced-cauliflower, marinara, and mozzarella; bake at 375°F (190°C) for 35–40 min.
GRILLED
Quarter, brush with oil, and grill 4–5 min per side for char and soft texture—perfect for kebabs.
SAUTÉED WITH ONIONS
Sauté with onions in olive oil or butter; season with Italian herbs. Great over sausages or steak.
FRESH HUMMUS BOAT
Halve lengthwise and fill with keto-friendly hummus (or cauliflower hummus); top with olive oil and paprika.
