In skillet, or Dutch oven, heat 1 Tbsp. olive oil over medium-high heat. Sauté onions, bell peppers and black olives until onions are translucent; remove and set aside.
In same skillet, sauté steaks in 1 Tbsp. olive oil until browned, being careful not to overcook (you just want to brown the meat). Season with Creole seasoning, garlic powder and salt & pepper all to taste. Continue with these directions until all of the meat is browned.
After meat is browned, set aside in deep casserole dish. Again, in same pan meat was cooked; stir together cream of mushroom soup, beefy onion soup mix, beef broth, Ro-Tel, Clamato and cooking sherry until blended; all to make a gravy. Pour onion mix over meat then add gravy mix.
Cover casserole dish with foil and cook in preheated 350°F oven for 1-1/2 to 2 hours. Serve over a bed of dirty rice (white rice or pasta may be substituted, but why would you want to; LOL)
For a vegetable I suggest slicing some yellow squash, zucchini, onions, mushrooms, and cutting a tomato into chunks (the quantity of squash and zucchini should be about the same). Add a little bit of oregano, Italian seasoning, seasoned salt, minced garlic and some tomato sauce (don't overdo it with the sauce, just enought to coat all of the vegetables). Broil (in the oven or on a grill) in a cast iron skillet. Very tasty!!
