  • 12 ounces veggie meatless ground beef crumbles - 1 package
  • 56 ounces 28 ounces each diced tomatoes - - 2 cans - 28 ounces each
  • 24 ounces tomato paste - I found - 4 cans 6 ounces each
  • 18 ounces water
  • 2 tablespoons extra virgin olive oil
  • 2 cups yellow onions, finely diced
  • 4 cloves garlic, finely diced
  • 1 teaspoon crumbled bay leaf
  • 2 tablespoons coconut sugar
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper


  • Put the oil in a large skillet and heat to medium-low.
  • Add the onion and sauté until it is translucent. About 10 minutes.
  • Add the garlic and cook 5 more minutes. It really does make the sauce taste better to sauté first.
  • Add all of the ingredients to the slow cooker except the frozen meatless crumbles.
  • Cook on low for 6 to 8 hours adding the frozen meatless crumbles the last two hours.
  • If you want to cook on high then cook 3 to 4 hours adding the frozen meatless crumbles the last hour.
  • Serve hot!


Let cool to room temperature. Package in rigid sided containers as defined in my article How to Prepare Food for the Freezer
I freeze it in freezer jars and it keeps the sauce neat and contained in the freezer.
Remove from the freezer and put in the refrigerator overnight because it is a pretty solid mass and will take longer to defrost.
Put all in a large saucepan and heat o boiling and then turn down the heat for about 5 minutes.
Cover with a splash guard to play it safe and keep everything cleaner on the stovetop.
