The post for Part 1 of Hot Sandwich Week was a beef & horseradish recipe for Eric. Today’s Part 2 post is for Andrew as the pesto used in today’s chicken recipe is his favorite condiment. Andrew’s love of pesto began more than 25 years ago. Eric participated in a cooking class where the appetizer was a pesto pizza. That simple pizza of a tortilla spread with pesto, sprinkled with goat cheese or feta, then baked until crispy, became a favorite of both our kids. It also established Andrew’s dedication to the condiment.
This recipe starts with chicken breasts, mushrooms, a bell pepper, and zucchini being slow cooked together in an herby tomato and red wine vinegar broth. Once cooked, the chicken is thinly sliced. Crispy & chewy ciabatta rolls are slathered with a mayonnaise and pesto spread then topped with the savory chicken and vegetable filling. It makes for a delightfully delicious, Italian inspired meal!
