Turn your oven to 350, toss bread cubes with olive oil and crushed garlic. Roast for 10 minutes, toss, and then an additional 10 minutes or until nice and crisp but not burnt. Remove and allow to cool. A third to one half should be reserved for crouton garnish.
Place all ingredients (including 2/3 - 1/2 of the croutons and all the roasted garlic) into a large bowl and toss well with your hands. Cover with plastic wrap, and allow to sit for at least an hour for the ingredients to soften and the flavors to come together.
Add to Vitamix or blender in batches.If needed, add some water to thin it out and blend until very smooth. Taste to adjust seasoning. Serve cold with extra croutons. or sliced tomatoes on top.
This taste even better the second day. Keep in mason jars in your fridge for lunch!
