First, slice your heirloom tomatoes into slices about 1/4 - 1/2" thick. It doesn't have to be exact.
Place the slices on a baking sheet lined with a clean towel or paper towels. Sprinkle each slice with a pinch of salt, turning them around so you can get both sides of each tomato slice.
Let the tomatoes rest while you're preparing the rest of this recipe.
Vegetarian Caesar Dressing
Now, prep the dressing. Add the garlic clove by itself to the food processor, and process on high until the garlic is finely chopped. Then, add in the juice from 1 lemon and stir it around so that the garlic is coated. Let this sit in the food processor for 5 minutes (this helps take the raw bite out of the garlic).
Then, add all of the other dressing ingredients, and process on high until smooth and creamy. When done, set aside.
Putting It All Together
Taking another clean towel or paper towel, pat the tomato slices dry, removing any moisture that the salt brought out.
Then, arrange the tomatoes on your serving dish.
Drizzle as much dressing on the salad as you'd like, then top with capers, chopped parsley, and a sprinkle of maldon salt (if you'd like).
Serve and enjoy!
Notes
Even if you don't like capers, DON'T skip them in the dressing recipe!! They provide a very-much needed flavor to the caesar. However, you can omit them as a garnish if you'd like.
Use capers in brine for this recipe, not dried ones. When adding them to the salad dressing, drain out most of the brine from your tablespoon (a little is okay).
