Cook tots on cookie sheet per directions on package, then transfer into something that crowds them up and can go into oven (CI skillet). Sprinkle with grated sharp cheddar and put back in oven for just a minute or two until the cheese is melted. A pinch of chopped green onions (and bacon bits) and it's good to go.
I served it right in the skillet, people like scooping out of the skillet and it keeps it warm for a little while. Don't forget the sour cream for dipping. Super easy and good.
