For all vegetables choose a way to cut: sliced rounds, halved, or quartered chunks. I prefer smaller pieces because it makes it easier to spear multiple vegetables at a time. You can slice strings of onions or dice. Peel cucumber to your liking or keep peel on. I prefer to peel, leaving small strips of peel on to decrease possible bitterness but still give more texture.
Add prepared vegetables to a medium-sized bowl. In a separate bowl combine oil, apple cider vinegar, balsamic vinegar, dill, garlic granules, sea salt.
Add seasoning mix into vegetable bowl and gently mix. Chill in fridge to let season for at least 10 minutes. Serve cold.
