My housemate and I plan our meals for the week and grocery shop together every Sunday. Now, instead of the added stress we'd normally experience when trying to figure out what to eat every night with barely anything in the fridge (and most likely ordering in), we're able to eat healthy AND have leftovers for lunch instead of scavenging at the office or (again) eating out.
We're saving money, eating better and saving time. We're also able to save on gas by going to the grocery store once/together instead of separately multiple times.
ALSO helpful hint- if you've ever done a meal kit program like Hello Fresh, save the recipes for super easy meal ideas!
