Start by boiling the garbanzo bean rotini pasta according to the package instructions. Once the pasta becomes tender, drain it in a colander and rinse it with cold water. This step stops the cooking process and keeps the pasta from sticking together.
In a medium bowl, combine the orange juice, peanut butter, rice vinegar, liquid aminos, maple syrup, minced garlic, and sriracha. Whisk everything together until the mixture becomes smooth and creamy. The dressing should have a balanced flavor that is nutty, slightly sweet, and tangy.
Place the cooked pasta in a large mixing bowl along with chopped cabbage, shredded carrots, cucumber, and sliced scallions. Pour the peanut dressing over the ingredients and gently toss everything together. Make sure the dressing coats all the pasta and vegetables evenly.
You can serve the salad right away, but letting it chill for about 20 minutes makes the flavors blend better. The dressing soaks into the pasta and vegetables, creating a richer taste. Give the salad a quick toss before serving.
