A crispy baked fish topped with a cheesy crab and pepper mixture. Easy to make, and nice to look at. This topping can also be used to stuff mushrooms. You may use any type of cheese that you like in this recipe - Italian cheeses work especially well.

Maine Lobster Lasagna

I made up this recipe because my hubby wanted to try a lasagna made with lobster meat. I combine tender steamed Maine lobster chunks in between pasta, jarred or homemade Alfredo Sauce and fresh spinach and ricotta, Cheddar and Parmesan cheeses. Serve with a tossed garden salad and oven toasted garlic bread.
