Here is my recipe for low fat Caesar salad dressing. It uses no fat!
Mix all of these in a blender, food processor or with an immersion blender (braun stick blender).
2 large cloves of ROASTED garlic (I bring home 3 heads at a time, roast them in a 350 oven for 45 mintues with the tops cut off and then seperate the cloves and freeze them in a ziplock bag, then I have roasted garlic whenever I want it!)
2 tbsp lemon juice
2 tbsp white wine vinegar (or balsamic, depends on your taste)
1/2 tsp worcestershire sauce
1/2 tsp anchovy paste (one tube lasts me a year)
2 tbsp grated parmesan (just throw in a 1 inch cube cut up a bit, the blender or processor will take care of the rest)
1/2 cup fat free plain yogurt
2 tbsp - 1/4 cup of low fat sour cream (if I have it on hand)
If I want to make it southwestern style and give it a little heat then I'll add a few shots of tabassco sauce.
I'll mix this with some mayo to make a sauce to put on salmon (it was serious delicious) and I add a shot of cayenne pepper just to make the heat stand up to the bold taste of the salmon.
I always make this a few hours ahead, if not a whole day ahead, so the flavours can really come together. I keep the leftovers in the fridge for about 5 days.
