Whisk together the baking mix, milk, eggs, and half of the butter until smooth. Let rest for 10 minutes.
Heat a 7-inch non-stick skillet over medium heat. Brush it with a little of the remaining butter. Pour 2 tablespoons of the batter into the pan, swirling it so the batter evenly covers the bottom of the pan. The first one may not work out so just eat it. Repeat with the remaining butter and batter, stacking the finished crepes onto a plate.
Preheat the broiler. Put a crepe on your work surface and run about 2 tablespoons of the chicken and gravy down the middle. Roll the crepe up and place it, seam side down, into a baking dish. When you have eight assembled, sprinkle the cheese evenly over the top. Broil until the cheese is melted and bubbling, about 1 to 2 minutes.
Separate the chicken legs from the thighs, and season with salt and pepper, to taste. Coat the pieces with the flour, shaking off any excess and reserve the leftover flour. Put the oil into a heavy bottomed skillet and heat it over medium-high heat. Add the chicken and brown it on all sides, about 5 minutes per side. Remove the chicken to a plate and add the carrots, celery, onion, mushrooms, and corn. Sprinkle with the reserved flour, and give it a good stir. Add chicken broth and stir. Nestle the chicken pieces into the vegetables and add enough water to just cover the chicken. Bring to a boil, reduce the heat, cover, and simmer for 20 minutes.
Just before the cooking time is up combine the baking mix, poultry seasoning, and milk in a small bowl. Drop the batter by tablespoons on top of the simmering chicken leaving some room between the dumplings. Cover and simmer for 20 minutes. Serve hot.
Heat 1 tablespoon of the oil in a large skillet over medium-high heat. Add the onion and saute until soft, about 6 minutes. Put 1/2 of the onion in a large bowl and the remainder in another bowl. In the large bowl add the beef, bread crumbs, grill seasoning, Worcestershire sauce and the egg. Mix to combine everything well and form the mixture into 5 oval patties. Heat the remaining tablespoon of oil in the same skillet over medium-high heat. Cook the patties until they are well browned, about 4 to 5 minutes per side. Remove the steaks and pour off all but 2 tablespoons the fat. (The patties will not be cooked through and will finish cooking in the gravy.)
Put the pan back on the heat, add the mushrooms, and cook for 5 minutes. Add the remaining onions, sprinkle in the flour, and cook for 2 minutes. Add the beef broth and bring it to a boil. Return the patties to the pan, reduce the heat to a simmer and cook until the sauce has thickened and the steaks are cooked through, about 10 minutes.
The extra crepes can be put between pieces of wax paper and frozen for later use.
