Tuna and corn are a wonderful combination. A cross between a souffle and a quiche, this easy dish is like elegant comfort food.
Preheat oven to 350 degrees. Combine the egg and milk in a medium saucepan. Add the corn and heat over medium heat until hot and bubbly. Stir in tuna, fine cracker crumbs, onion, salt and pepper. Pour into a buttered 1 quart casserole dish. Toss the melted butter with the coarse cracker crumbs and sprinkle on casserole. Bake for 20 minutes.
