Saute onions in olive oil over medium heat for 3-5 minutes, until translucent.
Turn heat up to medium-high, add the ground beef substitute and Italian seasoning to pot, and cook for about 5 minutes or until the meat is no longer pink.
Add crushed tomatoes and salt to the pot and simmer for 10 minutes.
While the sauce is cooking, lightly saute the spiralized zoodles until just softened, about 2-4 minutes or per package directions.
Serve zoodles topped with the tomato sauce. Garnish with fresh basil or cheese alternative if desired (macros not included.)
Store leftovers in an air-tight container in the refrigerator for up to 3-5 days.
