Yes, you can simply buy a package of taco seasoning, but then you have to try different products to see which one works for you (I'm a fan of McCormick's HOT taco seasoning). Or you can make your own. I tend to double it and make 2 pounds of taco meat because it freezes well. Try to find 90% lean ground beef or less. I've never tried ground turkey, but with all the seasonings in it your family probably wouldn't know the difference unless you told them!
1 lb. ground beef
1 Tbls. dried minced onion
3 Tbls. chili powder
1/2 tsp. cumin
3/4 cup water
Brown ground beef, drain fat. Add onion and spices, stir to coat. Add water and bring to simmer. Cook mixture, stirring occasionally, until thickened. Adjust seasonings according to taste.
We tend to leave it a little on the wet side instead of cooking until dry.
All you need are crispy tacos or flour tortillas, shredded lettuce, tomatoes, cheese and salsa. Enjoy!
