Foil Packet Tilapia (in crockpot), rice pilaf, cooked carrots

I have been trying several recipes in the crock pot. I thought fish in the crock pot sounded interesting and worth a try. I think this was okay, but not my favorite. It didn't look very appetizing either. Here's the recipe nonetheless. It's also from www.crockpot365.com

-- 3 or 4 fillets of Tilapia (or other favorite white fish)
--1/4 cup mayonnaise
--1/2 cup shredded Parmesan cheese
--juice of 2 lemons
--4 chopped garlic cloves
--pinch each of salt and black pepper

The Directions:
--mix all ingredients (except for the fish) in a bowl
--lay out a piece of foil
--rub sauce mixture on both sides of fish
--fold foil over and make a little packet for the fish
--put all the packets into the crockpot
--cook on LOW for 2-4 hours; fish should flake easily with a fork
