I made this great dish last night with fresh fettucine in a Thai chili-peanut sauce with grilled flank steak on top. There were tons of leftovers. Before I grilled the steak, I sliced it into pieces of about 1/4 inch. The steak was excellent, charred on the outside and medium-rare in the middle.
What's the best way to reheat this? Putting it in the microwave will get it too cooked in the middle and the char will get soggy. Putting it in the oven or toaster oven will keep the char but overcook it. What about regrilling it?
I'm at a loss. Should I just eat it cold?
