I bought a package of pepper steak and would like to cook it ahead of time, preferably in the slow cooker. I googled "pepper steak in the slow cooker" but the steaks in the ingredient lists are flank. The steak that I bought today is labeled "kosher beef pepper steak/shoulder". Can I use this cut in place of flank? If not, does anyone have a recipe for pepper steak that can be prepped in advance?
