Kidney beans? half a unit for 2tbsps yes? But on the tin it says 100cals and 0.5g fat per 100g which is half a unit...yes? I drain, rinse and weigh the contents of the whole tin and it's 255g...I'm telling you there is way more than 6tbsp in there..so what do I do? I'm saying 1.5 units for the tin...it's kidney beans not pure milk chocolate after all!
