Cheapest food per cost unit?

What's the best ratio of healing to cost foods?

I.E., if cake heals 12, and costs 24, it has heal to cost ratio of .5.

But cake takes forever to eat, too.

Anyway, gimme some F2p and P2p recommendations please.

(This is for healing after pking)

To train, I always use either trout, salmon or tuna.
