What kind of salad dressings do you like? I am all for making your own of everything. I think the more processed an item is the bigger chance of contamination. I would buy organic tomatoes (if you can find them) and make your own pizza sauce. I have a garden and grow mine and can them, so I have tomatoes to use this time of year. (I know that doesn't help you now) There are many salad dressings that are very easy to make. I would just google salad dressing recipes and see if you can adapt to your way of eating. If you let me know what kind you like I will see if I can find any recipes for you.
