In skillet, saute onions in the olive oil until softened. Add the stew beef cubes, stir to coat with the onions and oil. Add the water and simmer until tender, appx. 1 hour.

Preheat oven to 350 degrees. Pour meat mixture into baking dish. Cover with the potatoes. Mix the sour cream, soup, milk, garlic and salt and pepper and pour over the potatoes and meat. Sprinkle the cheese on top followed by the crushed Wheaties. Cover and bake for 1 hour. Remove cover, lower oven temperature to 300 degrees and bake for 30 more minutes.

Hint: We found that 1 cup of crushed Wheaties was not quite enough to cover the casserole, so you might want to add another cup. We had dinner guests from Michigan and Ohio to taste test this dish and it was a huge hit with them!
