Most jarred marinara sauces contain sugar. It’s so not necessary. Why not make your own marinara? It’s delicious, simple, freezes well, and can be used for pizza, lasagna, or pasta. This sauce is a bit chunky. If you want it smooth, simply allow it to cool and puree it in the pot using a stick blender. When the season permits, this is a great recipe for tomato sauce made with fresh tomatoes – enjoy!
