If you have a nice little baking dish to bake this in, it will make a beautiful presentation.
2 cans of crabmeat (or 1 large can of lobster meat)
1 block of cream cheese (room temperature)
1 cup of grated cheddar
1 cup of mayo
¼ cup of diced onion
2 tsp of dill
Salt and pepper
Mix everything together well. Let sit for the day or overnight. You can stuff into a bread bowl or in a 9x9 baking dish (approximate) and bake in a 350 oven for 30 min. Serve with crackers and/or sliced baguette.
