This tip from Chef Cora is probably my favourite of all, as it validates what I already do: buy precut and premade foods.
"There are so many high-quality options on the market now, with stores like Whole Foods and other high-end fresh grocers that have prechopped produce or precooked meals. Sure, they might cost a little extra, but if you can afford to splurge, this is a great option for it."
She highly recommends buying your vegetables precut so you don't have to prep before you cook and buying your fruit ready to go so you can snack on it when you get hungry. She included cooked meats and even whole meals as great options because many quality grocery stores prepare the food as you would at home without any hidden ingredients that would throw off your SmartPoints tracking.
