Corn Dog Casserole

Yup. You read right. I seldom make anything called a casserole and this recipe is fairly, erm... low brow. But. What I love about the Stampede can be counted on one hand. Top spot belongs to the Corn Dog. This casserole is really good and you don't have to endure any of the Stampede shenanigans to get it.
1 small onion, finely diced
2 cups celery, thinly sliced
1 bunch green onions, chopped
2 Tbsp butter
1 package of weiners (sausage would be good too, but if you get the fresh sausage, made sure you cook it all the way through first.
1 package of corn bread (or muffin) mix (or use your own from scratch recipe for a dozen muffins or a 8 in square pan)
1 egg (follow package directions)
1 cup milk (follow package directions)
2 cups of grated cheddar cheese

In a medium skillet, saute onions and celery in butter until they're soft. Meanwhile, slice wieners lengthwise into quarters, then cut into thirds. Add to onion mixture. Set aside 1 cup of mixture.
Mix the cornbread or muffins according to the package directions with egg and water or whatever your package calls for. Stir in all but the reserved wiener mixture and 1 1/2 cups of the shredded cheese. Spread in a casserole dish, then top with green onions, the rest of the wiener mixture and the rest of the cheese-in that order so the cheese melts on top.
Bake in a 400F oven for about 30 minutes. Serve with mustard and eat while wearing your best cowboy hat. Or not. :)
