Popcorn!
A little while ago DD and a few pals appeared in my house searching nibbles. We don't have many snacky foods in because DH can't resist them... but he's never noticed the innocent little bag of popping corn lurking in the cupboard
It has to be about the easiest crowd pleaser going, and healthier than crisps etc.
just 1/4 cup in a large bowl, cover with a splatter guard, nuke for a couple of mins, scoop out popped corns, nuke again for another min to get most of the rest done.
You don't need oil. You certainly don't need brown paper bags which seem to figure in all the online recipes I've seen.
Just a bit of salt. (or on my serving pepper and parmesan cheese. Guiltless yum!)
