The best part is you add your own salt, spices, flavorings as you like and
there are a lot of good types of popcorn out there with different tastes
and textures so you aren't stuck with the same old poison that Orville
and the rest are peddling.

Tip:

Use a small glass casserole dish with a cover to microwave vegetables in.

Never heat anything in plastics or covered in plastic wrap.
