Sometimes when I do nachos with a bunch of stuff on them, they get a little soggy. I like just cheddar melted in the oven on some home fried corn tortilla chips. Then put the other stuff on the side to dip into.
Once, I had used chipotle in adobo sauce for something, had strained it into a smooth paste. The leftover stuff I put into some canola oil, let sit in the fridge for a week. Then used that oil to drizzle over refried beans, nachos, etc. Just a bit goes a long way. sooooo yummy!
I like onion, jalapeno, cilantro, chopped and mixed together with a bit of lime juice. Green onions are nice, too.
