Dressing: Add all ingredients to a glass jar and shake until combined.
Croutons: Set oven temp to 375F. Rub each piece of bread with cut side of garlic, drizzle with olive oil then sprinkle with Parmesan cheese. Toast in oven for 10-12 minutes, or until golden brown. Slice into cubes and set aside.
Salad: Place tomatoes, olives, herbs and avocado into large bowl and add dressing then toss. Add the bread and toss again to combine. Allow to sit for 15 minutes for the flavours to develop and for the bread to soften.
