Preheat the oven to 400 degrees F. The best order of operations is to prep the roasted garlic for the Creamy Garlic Dip first. Remove any excess papery skin (but not all of it) from around the head of garlic. Slice about ¼" off the top, then drizzle olive oil into the cloves and rub the head with your fingers to spread around the oil. Wrap it in foil, place directly on the center rack of the oven, and roast for ~30 minutes until tender. Remove from oven and carefully squeeze the tender cloves into a blender. Add the white beans, nutritional yeast, oregano, and lemon juice. Blend on low, drizzling olive oil into the mixture as needed to promote blending. Taste and adjust seasonings as desired. Spoon into one of the serving bowls for the veggie platter.
Next, make the veggie chips. Line a baking sheet with parchment paper or foil. Spread the thinly sliced veggies (sweet potato, beet, zucchini, carrot, etc.) on top. Lightly toss in olive oil, and dust with paprika, garlic powder, salt, and pepper. Bake for 15 to 20 minutes, flipping halfway if needed, or until the chips are crispy. Remove from oven and arrange on the veggie tray.
Finally, make the Greek Yogurt Cucumber dip by stirring together all of the ingredients in a mixing bowl. Transfer to a serving bowl.
Arrange the rest of the veggies (raw, cooked, or pickled) on the platter. Enjoy!
