Slow Cooker Warm Pastrami Sandwiches
I grew up in Southern California and there is this fantastic little dive of a restaurant called The Hat in Upland CA that makes the most delicious pastrami sandwiches I have ever had.
Now I live 1,175 miles away in North Eastern Wyoming. But, I still crave a good warm pastrami sandwich from time to time. So, I make them myself and I use my slow cooker to heat up the meat in a beefy mustardy broth.
To eat, I slather a hoagie style roll (good on rye bread too) with more mustard, some cheese and I pile on the pastrami meat.
Then I take a little bit of that au jus from the crockpot and ladle it into a small bowl and I dip my sandwich in it and take a big satisfying bite!
Served with pickles and chips this makes a great lunch or a light dinner. It is perfect for busy days like lunch after church or for hot summer days when you don’t want to think about using the stove or oven to make dinner.
Give this recipe a try. I hope you love it as much as my family and I do!
