Start by gathering fresh carrots, cucumbers, and radishes. Wash them thoroughly under cold water, then slice the carrots into matchsticks and cut the cucumbers into thin rounds or sticks. For the radishes, you can slice them into rounds as well. Aim for uniform sizes to ensure even pickling.

Next, grab a medium saucepan and combine one cup of water with one cup of vinegar over medium heat. Bring the mixture to a gentle boil, stirring occasionally. Add chopped green onions, minced garlic, sea salt, oregano, and sugar, mixing until the sugar is fully dissolved.

In a clean mason jar, layer the prepared vegetables in a colorful arrangement. Pour the warm vinegar brine mixture over the veggies, ensuring they are fully submerged. Gently press down on the vegetables with a spoon to release air bubbles.

Allow the filled mason jar to cool at room temperature for about 10-15 minutes. Once cool to the touch, cover the jar and place it in the refrigerator.

Your Quick Fridge Pickled Vegetables are now ready to enjoy! Letting them sit for a few hours or overnight allows the flavors to deepen.
