May not be PC in the Hunting Forum, but my favorite is salmon. A fresh Kokanee (more available than sea-run here in ID) marinated and grilled, beats anything on 4 legs (or two wings). IMHO.
Healthy, too. Low fat, lots of vit. E, etc.
Trout comes in 2nd.
Also enjoy Chukar and Pheasant. Haven't tried any of those tasty-sounding duck recipes from the forum, yet. No chance to hunt 'em yet :-(
