re: What’s the best way to prepare Eye of Round Roast?

Bulgoki.

I get it almost frozen then run it through the meat slicer at 7mm, across the grain of course.

Make a marinade:
1 cup soy sauce
3 toes chopped garlic
grated ginger
tablespoon honey or br. sugar
pepper flakes
tablespoon sesame oil
chop 3 green onions

Stir this into the meat, coating it well.

You only have to marinade about an hour since the meat is thin.

Get your grill very hot, then lay as many pieces as you can. By the time you lay them out they are ready to flip. I store in an ice bucket to keep hot until serving.
