Colorful winter kale pesto and tangy red onion tart
This winter kale pesto and tangy red onion tart combine a garlicky pesto made from kale, a creamy mustard bechamel sauce, tangy macerated red onions atop a store-bought frozen pie crust. It’s as much a treat for the eyes as it is the belly. So grab your food processor, a pan and a baking sheet.
