DELICIOUS! Perfect recipe! The only thing I had to change was using a Pomodoro sauce instead of a marina because it’s what I had in the pantry- frankly, they’re probably the same thing. Otherwise, I followed the instructions precisely and it turned out fabulous. Thanks for another great recipe!
Easy and delicious!
