Home made dog food

Looking for advice on making a nutritious home made dog food. I boiled the carcass from our turkey for a base. We have more than 3/4 of a turkey left over plus I bought an extra one for the dog. I have sweet potatoes, frozen peas & frozen green beans, carrots, ginger 🫚 (not the spice) I have omega 3 in a bottle & turmeric. I just dont know how much of everything to put in and what else I can add. If anyone has a recipe they use and are willing to share, I would be greatful.

I know that onions and garlic are bad for dogs. What else can I put it it to make it nutritious and delicious for him. He is 12.5 so he needs high protein. He also has joint pain, hence the tumeric. I want to get away from canned dog food as most of it upsets his belly and gives him gas. He is prone to allergies, so I am taking him off of chicken to start and getting a special chicken free kibble for sensitive stomachs and skin.

I should add that I have ordered 5strands allergy test to see what he is allergic to but in the meantime, I have all of this leftover turkey and want to give it a go
