Hmm, OP says most delicious...steak is my favorite.
ALL things considered I'd have to say
1)Chicken: Delicious, fairly inexpensive, healthy, I don't get tired of it, fairly high in protein
-takes a while to cook
2)Salmon: I'm from Seattle and a few of my neighbors are native american...I can't help but love great salmon.
delicious, healthy
-pricey
3)Pork: Delicious, naturally sweet, cheap, easy to cook
-unhealthy
4)Beef: STEAK!!, cheap, high in protein
-Don't care for ground beef, unhealthy
5) Venison: Delicious
-pricey, rare
