I like using the frozen O'Brien potatoes in a breakfast skillet. I brown a pound of breakfast sausage, then dump in the O'Brien mix and brown it. Then I push all of it to the back of the skillet, slide the skillet back so it's half off the burner, and scramble a dozen eggs in the front. Then mix it all together and melt some shredded Colby Jack onto it.
That's for large groups.
If it's just the family, I'll brown the pound of sausage, but remove most of it and put it in the fridge to cool. Then I'll follow the above procedure with part of the o'Brien mix and a few eggs.
After the leftover sausage cools I add it to the leftover O'Brien mix and put it back in the freezer for next time.
The O'Brien mix has broken apart pretty well for me, so far.
