Ingredients

Nonstick spray for pans
30 pounds lean sirloin tips
2 tablespoons salt, pepper to taste
1 cup vegetable oil
4 pounds onions, diced (can do more)
10 bell peppers diced
7 1/2 quarts beef broth
120 ounces mushrooms, drained
2 1/2 cups cold water
2 1/2 cups flour
10 pints Sour Cream
May garnish with paprika

Directions

Cut the meat into 1-inch cubes; salt and pepper to taste. Spray oven-proof casseroles or steam pans with lids, with nonstick cooking spray. Add oil to the pan on the stove top. Brown the meat in the oil. Add the chopped onions and bell peppers to beef and sauté lightly. Then add the beef broth and the drained mushrooms to the meat mixture. Cover the pans and bake in a preheated 350 degrees oven for 40-50 minutes. Mix the water and the flour; stir into the beef mixture, dividing for the pans. Bake for an additional 15-20 minutes. Stir and check thickening. If thickened, remove from the oven. Stir in the sour cream until incorporated. Serve over cooked rice or noodles.
