I love fresh green beans and this is a "recipe" I've thrown together many times. My family loves it. I use my large Pampered Chef micro-cooker for these. I apologize that I don't have any measurements.
A bunch of green beans (maybe a pound??)
A big glob of butter or margarine (1-2 Tbls)
A big splash of soy sauce (maybe a Tbls?)
A couple of spoonfuls of garlic (maybe a Tbls again)
I also added a small splash of sesame oil this last time with success
Be sure to add the lid and cook for 4-6 minutes depending on desired tenderness.
