For those pesco-vegetarians, here is a great recipe that can be used with crab or shrimp.
1 ripe avocado
jumbo lump crab meat
Swiss, cheddar or gruyere cheese, sliced or shredded
Cut avocado in half and remove pit. Stuff grilled shrimp or lump crab meat in the hole where the pit was. Cover with your choice of cheese. Sprinkle with Italian seasoning. Place the avocado halves in the oven on broil. Watch closely and when cheese starts to brown/bubble, remove and enjoy!
