Heat the vegetable oil in a skillet over medium heat. Add the green pepper and saute for 5 minutes. Add the chopped hot dogs and turmeric powder; stir will and saute for 5 minutes. Add the mushroom and crushed tomatoes and cook uncovered until almost all the liquid is absorbed, about 20 minutes. Set the mixture aside.
Preheat oven to 350 degrees F. Place the slices of bread on a cookie sheet and toast in the oven until a little crispy, about 4-5 minutes (keep a close watch on them).
Then spread the garlic tomato sauce over each bread (not too much).
Top with the mixture and sprinkle with dried oregano leaves.
Then top with the mozzarella cheese. Preheat oven again to 350 degrees F. Place the pizza toasts on the cookie sheet. Put them in the oven and bake until cheese is melted. Serve immediately.
