Since posting the recipe, I have made this sauce many, many times. We have done a few variations of the recipe as well:
I personally didn't like it as much with ground turkey. The sauce itself was still delicious, but every time I bit into a chunk of turkey, I wished it was beef. I know turkey is healthier, but I just don't really like it. I'd rather have beef less often instead. My brother Ben, however, makes everything with ground turkey, so I'm sure he likes it that way.
A while back, Thomas and I decided to have red meat only once a week and to eat at least one meatless meal a week too. Consequently, I've adapated a number of our recipes to be made with chicken or without meat at all. To make this recipe vegetarian, I (obviously) cut out the beef and add extra onion, a red pepper as well as a green, and a zucchini. It is DELICIOUS. We don't even miss the meat when we have it this way.
half beef/half pork
Tonight, at the recommendation of some friends, we are making the sauce with a mixture of ground beef and ground pork. I tasted it a few minutes ago, and I think it's going to be amazing! We're also planning to try it just with ground pork. I'll let you know how it goes.
Update: The beef/pork combination was super tasty. I didn't know how Jamie would do with the chunks in the sauce, so I blended some sauce for him and put it on macaroni noodles (they are easier to pick up than spaghetti). He gobbled it down and made the biggest mess!
