Here is a simple storage tip.

I keep a lot of pint size canning jars on hand with lids and rings. Assuming it is taco night I will have left over diced jalapenos and maybe rotel. Instead of throwing them away, I put them pint jars and put them in the fridge. I just mix them all up in the same jar.
From then on, I have them available for any dish I want to pep up. It just doesn't seem right to throw them away.
I use them a lot on scrambled eggs.
Now Rotel has a habanero version out. I found it at Mac's.
