What tempeh to use

Personally, I love the tempeh from Trader Joe’s. It has minimal ingredients, is reasonably priced, and also crumbles really nicely/easily. Bonus, it also stays good for a long time in your fridge!

How to make this Vegan + Vegetarian Spaghetti Sauce

  1. Saute onions – in olive oil over medium heat in a saute pan until clear, ~2-3 minutes.
  2. Add crumbled tempeh – and continue to cook until all pieces are browned, ~5-6 minutes.
  3. Add mushrooms and green pepper – cook until mushrooms are no longer ‘pink,’ ~3-5 minutes.
  4. Remaining ingredients – get added to pan. Bring to a low boil and then simmer uncovered on low for 20 minutes to allow flavors to combine and sauce to thicken. Stir occasionally to make sure sauce doesn’t burn/stick to bottom.
  5. Prepare your base – for this recipe, I used zucchini noodles, but you could also serve over roasted potatoes, or your favorite brand of regular or gluten free pasta.
  6. Serve – once sauce is ready, serve over base of choice. Optional, top with fresh basil and your choice of cheese!
