Meal prepping is great practice for a number of reasons. It can help you eat more healthily, and save you lots of time and money. According to Business Insider, having the right tools can help you save even more time and hassle when you're doing the actually meal preparation. A large, sturdy baking sheet is invaluable for roasting vegetables, as is a slow cooker for making stews and soups. If you want to speed things up, consider a pressure cooker, Instant Pot, or Ninja Foodi.
