Notes
You should use any cooked sausage that you simply like. I purchase my sausage from a neighborhood Polish retailer, the place they make their very own sausage. It’s SO scrumptious. The sausage that I used this time had a extremely smoky taste, so it gave that very same smoky taste to the remainder of the greens. Nevertheless, you need to use any sort of sausage that you simply want.
