A week of protein from each

Budget says one, calories say the other
Edamame costs $0.033 per gram of protein against $0.055, so it saves $15.08 a week at a 100 g/day target. Sardines (canned in oil) answers a different question: 11.8 g of protein per 100 kcal against 9.9 g, which is what matters once calories, not dollars, are the thing you run out of first.
One of these is a convenience purchase
Sardines (canned in oil) ranks #22 of 25 on cost per gram of protein, near the bottom. It is not a bad food, it is an expensive way to buy protein: $1.65 per 30 g against $1.00 for edamame. If it is in your basket for the protein, swap it. If it is there because it travels well or you enjoy it, that is a different and perfectly good reason.
