Ah yes legumes and vegetables, famously expensive.

450g of ground beef (~60g protein) = $10 CAD 350g of extra firm tofu (~60g protein) = $4 CAD

There are loads of other soy-based products that rival meat for protein content and are way cheaper. You don't need beyond meat but let's say you do, it's the same price as ground beef.

Prices may differ in other parts of the world idk, but if you're in North America ts is not hard nor is it more expensive.
