I have been using ground turkey for many, many years. I use it in everything except meatloaf; which has to be ground chuck for me. I only buy ground chuck/beef when it is on a good sale. Lately it is way too expensive.
Oh yeah...I don't like turkey burger's either. Real ground chuck or ground chicken only and usually only in the summertime cooked on the grill.
With spaghetti, chili, tacos, soups etc the turkey is fine. I season it pretty heavily with garlic powder, onion powder, and chili powder. I also add veggies--onions, green peppers and carrots-- and a couple of tablespoons of milled flaxseed to it. My MIL has said she cant understand why my taco meat tastes better than hers...not ever telling her its the ground turkey. They turn up their nose to anything healthy.
