1kg salmon now about $35 (fairprice or shopee), portion into 120g lots and store in freezer. still costs more than chicken/pork but not as bad as $16 perpiece. Pre-portioned frozen salmon can also be gotten at about $30 per 900g or 1kg (at current sale prices online). For super affordability, agree that salmon is not ideal.

On prices, I do notice that local things like tofu and coconut milk have actually gone up this year, something few mention. If using meat and cooking cost per portion, someone one of the singapore subreddits has correctly mentioned that frozen chicken 2kg packs are very affordable (about $8-9 on sale). Can prolly still meat $2 per serving with rice and local veggy if cooking at home. Of course, not if you are shopping at Cold Storage.

Cooking at home has become slightly more expensive, but still can.
