Ree Drummond's new cookbook, "The Pioneer Woman Cooks: Dinner's Ready!" focuses on quick and easy dinners without sacrificing flavor. She uses store-bought shortcuts like pie crusts, salsa, and frozen fries, but emphasizes the importance of using them sparingly and not at the expense of taste. Drummond shares her favorite store-bought upgrades like jarred marinara sauce and frozen bread dough. She also suggests making "fridge grabs" like garlic confit and pickled red onions to add flavor with minimal effort. The cookbook is now available for purchase.
