If you're late in the planting season you can go for winter veggies. Potatoes and carrots can be planted when it's cold, and ready to harvest when its warm again. Kale stays green well into the snowy seasons.

Potatoes just needs a bucket or bag per potato, and soil and/or sand. Fill the bucket maybe halfway and hide the potato, then once it starts growing in the spring keep covering the all but the top part of the stem with new sand-soil until the bucket is full, then let finish growing. Water regularly once it thaws outside, but not while it's freezing.

I think I kept it cold but protected during winter, like a shed, but maybe I just left it outside? You can keep one bucket indoors and one outdoors and see if there are different results in the end. Bring both outside once there's sun and warmth to kickstart the growing.
