“Burgers and Fries,” episode 302 of Sara’s Weeknight Meals starts airing this week around the country. I’ll be making Spanish Style Burgers, Meatloaf Burgers and Oven Fries. But first I do some research at a Philly butcher shop to find the best burger grind and then visit a Philly restaurant to learn how to make their famous fries cooked in beef fat. You’ll find the recipes here.
