Dietitian Tip:

Preparing fresh vegetables on the weekend is a game-changer for busy weekdays. By washing, chopping, slicing, and storing vegetables in advance, you create an easy, grab-and-go solution for healthy meals and snacks throughout the week. Whether it’s for quick stir-fries, salads, roasted veggies or just something to munch on, having them prepped saves time and helps to eliminate the stress of meal prep during the week.
