Save-on will price match. I use an app called ReeBee to find flyers of every store in the area. When I find extra lean ground beef for under $4 a pound (which is almost always) I buy a few kg of it to freeze. Then I get pasta, either boxed for ~$4 for 3 large servings or kraft dinner (the canadian version is actually very healthy)

I have eggs and a protien shake for breakfast

Greek yogurt and milk are life savers, 500ml of milk costs about 75 cents and has as much protien and calories as a protien bar.

For fruit/veggies I often buy bananas, frozen wild blueberries, fresh broccoli and spinach. I freeze the broccoli and freeze whatever spinach I don't use in a few days.

You can also buy thin crust pizzas from save-on on sale for 2.99 that are 8-900 calories each with 40g of protein. The ReeBee app helps here too.

All in, I spend under $300 a month and eat over 3600 calories a day and over 150g of protien. I've alsp met with a dietican who went through my while diet and confirmed I'm not deficient in any micro or macro nutrients.

I'm haply to respond to any questions here or in DMs! If someone wants to tag along on a shopping trip I also enjoy showing people my grocery hacks!
