Tip: Sauce can be pureed using a cocktail blender if you do not have a hand immersion blender. Just be careful to not fill the blender more then 1/3 of the way full when adding a hot liquid. Start mixing by pulsing the blade slowly at first while holding your hand on the lid that is slightly vented to allow a crack of air into the blender bowl. This will prevent the lid from exploding off the blender (and all over you or your walls and ceiling) which can sometimes happen if you mix hot mixtures in a blender with a tightly closed lid.
Over time, eating a healthy, Mediterranean-like diet and foods rich in lean protein, omega 3 fatty acids, vitamin D, folic acid, Selenium, and magnesium are particularly helpful with improving mood and combating depression. This recipe provides a good source of many of these nutrients.
Heat a heavy-bottomed medium sized sauce pot over medium heat. Add the oil and heat until the oil has spread out to cover the bottom surface of the pan. Add onions and garlic to the pot, stir to coat mixture with the oil and continue to cook while stirring occasionally until onions are soft.
Add the vinegar, roasted peppers, water and saffron threads; bring mixture to a boil, reduce heat and simmer for about 8 to 10 minutes.
Remove pot from heat and using a hand immersion blender blend the mixture until smooth. Adjust seasoning with salt and pepper (optional).
