You can cut up into chunks, sprinkle with salt and leave in a colander for a while to drain off the bitterness. Rinse, pat dry with kicthen towel then roast as described with chopped peppers, corugettes, cherry tomatoes, onion etc. sprinkle with dried basil and oregano.
Otherwise perhaps you could cut in half, deseed and scoop out some flesh and roast in oven until starts to soften. Fill with chopped tomatoes, peppers etc drizzle with olive oil and continue to roast until cooked through. Sprinkle with grated cheese and grill to melt it ?
