Puffer food?

I make homemade food for my other fish tanks, but I wanted to start making some for my puffer too. I dont think he likes the food I make for the other fish because it has a lot of greens in it. What are the key ingredients I would need in food for my puffer? He's a figure 8 puffer btw. I was thinking it would be mostly shrimp, oysters, beef heart, vitamin supplements, stuff like that, but how much veggies should I put in? anything else important?
