I hope you are not getting tired of simple Makeahead ideas-it's just all I've got right now.
This recipe is from Pioneer Woman. It is my favorite spaghetti sauce right now because it is super meaty. I make a huge batch and then freeze it in smaller portions for future uses. The only thing I do differently is double the amount of tomatoes. I know her whole point is to have it meatier than tomatoier (a new word I just made up) but it is still plenty meaty even with the extra tomatoes. My mouth is watering as I type.
Here is the before:
And this is after it has simmered for a while (I don't always simmer as long as she recommends either-mostly because I never have that much time).
