GUMBO!!!! ... Holy trinity (green peppers, onions, celery), some Cajun Napalm (dark roux), stock, meats (steak, sausage...I like andouille or linguica, shrimp, whatevers. Literally.), tomatoes (Yes. I go there.)... There are literally hundreds of gumbo recipes. I never make mine the same way twice.
Chili Time... Make whatever red chili you ordinarily make (ground beef, bison, pork, etc), and then add the steak. I suppose you could do a white chili w steak, but I'm not feeling it for whatever reason. Green has potential, though.
Fajitas... Let marinate for a wee bit in some lime juice & cilantro. Sauté up some green peppers and onions.
Stuffed Peppers... I do Cajun stuffed peppers, which is essentially gumbo that I didn't want to eat for a week or seven (froze). But any stuffed pepper recipe.
