Mac & cheese

The kids wanted to make macaroni and cheese by themselves today.  They got out the box, followed the instructions, and were very happy with the results.  Now they don't want my mac & cheese anymore, because theirs is way better.  That's because I only use half the packet of cheese sauce and a tablespoon of butter, instead of the 4 tablespoons in the instructions.  Now they've tasted the rich goodness and don't want to go back to my healthier version.
