Corned Beef
Just because St. Patty's Day was a flop this year doesn't mean that people shouldn't be picking up their customary corned beef brisket. Although they aren't as good as their Jewish counterpart (pastrami, buddy), a good corned beef brisket will do in a pinch. Pro tip: if you soak it in fresh water, you can pull a lot of the brine out of the beef. This leaves you with tenderness, and then you can choose how you want to season it on your own.
Gnocchi
We think that people aren't buying gnocchi because they don't know what it is. However, we HOPE that people are just making gnocchi at home instead of spending six dollars on a pound of it. Seriously, you can make ten dollars worth of gnocchi for just under three dollars.
