/ck/ - Food & Cooking

Make him foods similar to what he likes, but homemade for starters.

Fried fast food tendies = oven baked breaded tendies. All frozen foods have an at home equivalent so just make those.
Start making salad and keeping some on hand for yourself and serve him some with dinner to get him use to greens. No spinach, use romaine or green leaf, butter leaf

You should be the one plating meals and bringing them to the table, so give him enough food for a man his size, and put the leftovers away before he eats to deter the thought of getting seconds.

He probably wont eat leftovers so dont bother meal prepping, just make fresh dinners nightly mimicking some of his favorite foods, with something different & green on the side and insist he tries it.

You could make something for yourself and ask him to taste it to see if it needs more seasoning too
