Growing your own fruits/veg is low effort and very rewarding.

Well worth it if you have a bit of time and have the space for it. We do a fruit/vegetable garden most years (In a fairly cold climate) and we've had a lot of success with zucchinis, apples, pumpkins, gooseberries, raspberries, asparagus, rhubarb, lettuce, peas, and a few others. It honestly tastes a lot better than most of the store-bought produce, plus there's a feeling of accomplishment as you see your food growing day by day.
