You don't always need to eat fresh produce, as frozen is just as good. "When overbuying fresh foods busts your grocery budget and leads to food waste, I recommend looking at frozen fruits and veggies. Frozen raspberries are picked at peak ripeness and processed right away to lock in and protect nutrients," says Moon. You can use frozen raspberries for smoothies or for a vinaigrette that's a little different. "They can also be added right into pancake and muffin mixes (whole grain, of course)," she adds.
