Hi I love making this raw zucchini spaghetti with a raw tomatoe sauce. When I make it it usualyy comes out good, but yesterday i dont know what i did differently. I make my sauce with tomatoes, 1 red bell pepper, oragano and basil thats it! When I added the sauce to the zucchini and mixed it around ,I got like foamy bubbles, I didnt like it at all. Does anyone get this too? What could of caused that foamy bubbles?
