did i mess up a good beef burgundy recipie by using real burgundy?

i cooked beef burgundy in a slow cooker by a recipe,and it turned out awful…the only thing i can think of that ruined it was using real burgundy wine instead of cooking burgundy..is that it,if i followed the recipe to a tee otherwise?(i got the recipe off Food Network‘s website..and everyone that had reviewed the recipe said it tasted excellent)

What is a good recipe to use chunks of beef tenderloin?

I recently bought a 4 pound whole beef tenderloin. I cut it up into a roast size portion, two steaks, and then I had just less than a pound of “stew meat size” pieces left. I am looking for a recipe that will make the most of the beef tenderloin chunks. I’ve tried allrecipes and food network, and I haven’t found what I’m looking for yet. Any suggestions??
After seeing these answers I should clarify.. this is good tender meat, I am not looking for anything that will cook it to death, like stew or crock pot recipes. The stir-fry and kebob ideas are closer…any more ideas?

Once I had Beef Tips Monterey in a restaurant. It was beef in a creamy sauce with cheese and onions I think, but I have no idea how to make that. Something along those lines is what I am looking for.
