My favorite is to blanch and peel a tomato, take out the seeds and chop, add to mayo, fresh dill, salt and pepper. Sprinkle white wine over the fillet and let sit for about 30 minutes. Dry off. Start meat side down on grill. Flip when crusted slather with sauce and close the lid. When the top of the may starts to brown it's done. Always a huge hit with my family
