Pastrami Sauerkraut Crostini

What is pastrami?

When’s the last time you had a hot pastrami sandwich? (So good). But wait … let’s back up. What is pastrami anyway (my kids just asked me)?

Pastrami is meat that is made from beef,  or sometimes from pork, mutton, or turkey. I know …. it tastes so good, right? The flavors come from the way the meat is processed. The raw meat is brined, partially dried, and then seasoned with herbs and spices. The last step is smoking and steaming the meat.

Another party hit are these Hot Pastrami Sliders, served with melted cheese and caramelized onions on pretzel rolls. Yes, please! :)

If you’re looking for a simple St. Patrick’s Day menu, I’ve put one together for you, here.

Even if you don’t have the sunshine in your corner of the world this week, you’re going to love the menu, starting with a few yummy appetizers, this Pastrami Sauerkraut Crostini, and my delish Irish Slaw Dip! And then there’s Skinnytaste’s Crock Pot Corned Beef and Cabbage, ending with RecipeGirl’s Irish Cream Bundt Cake! Oh, boy!
