Cooked meats as in ham, chicken, that sort of thing?
If so, do bear in mind that this isn't ideal long term, as these things don't have the taurine in that cats need in their diet to stay healthy. Cats cannot synthesize taurine like humans can, so they need to have it present in their diet.
If you are choosing a wet food, look for one that is labelled "complete". Anything that's described as "complimentary" or things like cooked meat should be more of a treat than a regular food.
At least the biscuits are "complete" though.
If you want to look for a wet food that's a bridge between cooked chicken, say, and reasonable quality wet food, you might want to try him on HiLife "Tempt Me". The chicken selection has proper bits of chicken in, but it's a complete cat food. IIRC you can get single pouches of this, so will save you buying a whole box.
In my experience, a cat will usually eat the first pouch of something out of curiosity. It's usually the *second* pouch that's the tipping point LOL
