Preheat the oven to 400-degrees. Form the sausage meat into 6 patties.
Simmer in a skillet with the 2-tablespoons water, keep covered. Remove
the cover, allow both sides to brown. Place the patties in a casserole dish
or an 8 x 8 x 2-inch cake pan. Brown the onions in the sausage fat. Place
the onions over the sausage. Combine the Tomato soup and water, mix well
and pour evenly over the top. In a bowl, blend the biscuit mix and milk,
creating a softened dough. Roll to fit the baking dish, and place over the
layered sausage, onion, soup. Lightly brush the dough with milk. Bake for
20 minutes.
