Creating Cucumber Sushi is straightforward if you follow these simple steps:

1. Prepare the Cucumbers: Slice the cucumbers lengthwise into thin strips using a vegetable peeler or mandoline. Aim for about 1/8 inch thick.
2. Lay Out the Fillings: On a clean surface, arrange the cucumber strips horizontally. Leave space at one end for rolling.
3. Add the Fillings: Place a few slices of avocado, bell pepper, carrot, and quinoa (if using) on each cucumber strip. Add cream cheese for an extra creamy texture if desired.
4. Roll the Sushi: Starting from the end with the fillings, carefully roll the cucumber to form a sushi roll. Use your fingers to hold the fillings in place while rolling.
5. Slice and Serve: Once rolled, use a sharp knife to cut the sushi into bite-sized pieces. Sprinkle with sesame seeds for added flavor and garnish.
