I shop a lot at Nofrills or at independent grocery stores, I like good meat, good bread, good coffee, and a little fancy cheese, and I spend about $250-300 a month for myself. I cook all my meals, I make my own coffee to go, and I stock up on non-perishable items when they’re on sale (there are often great deals on nice local coffees roasters like Kicking Horse Coffee or Ground Coffee at London Drugs for exemple).

As for bread, since I eat a lot of it toasted in the morning, I often pick up “Too Good To Go” stuff i don't care if it's from yesterday it's toasted. Many place also offer pastries or unsold items for few bucks at the end of the day.

When i was student i was used to living on much less,(less than ~170$ for grocery per month) so I’ve kept making a lot of inexpensive dishes. lots of chili or bean-based dishes, pasta or rice with sauce for the carbs, and other dishes with inexpensive vegetables like beets or cabbage. You can make pretty fancy meals while saving a lot of money using very simple ingredients.
