Slice cucumber in discs no more than 1/4" thick. If smaller pieces are desired, cut the cucumber in half lengthwise first. Cut each strip every 1/4 inch to form bite-sized pieces.
Slice off the top of the pepper. Slice the pepper in half and use your fingers or a knife to slice out the seeds and innards. Lay each half face down on the cutting board and slice the pepper into strips 1/4" in width.
Place the cucumbers and pepper into a bowl. Pour red wine vinegar into the mixture and sprinkle salt and pepper to taste. Make sure you stir in all ingredients/seasonings thoroughly.
Keep in fridge until ready to eat!
