That's 120 calories from protein and 90 calories from fat; is that the ration you want?
The bit about the cheaper parts of the turkey (and the dark meat) being ground in is true; ground turkey can have more saturated fat than the lean ground bef you buy. Get used to reading the nutritional info on all packages, and you can make smart choices.
And as for taste: go ahead and season anything you eat, all you want. Herbs and spices aren't adding calories, but they ARE making a meal a whole lot more interesting. Lean ground turkey in chili rather than lean ground beef won't alter the fact that it's chili-flavored.
