Start by cooking the pasta according to package directions, (3 cups dry pasta cooks in about 10-15 minutes).
Meanwhile, chop celery, red pepper, and red onion into fine dice. Chop cherry tomatoes in half. (The chopping doesn’t have to be precise, just to your liking!)
Make dressing by placing all of the ingredients in a sealed water bottle, or Tupperware container, and shake until everything is well combined.
Once pasta is done cooking, place in a strainer, and rinse with cool water. Add pasta to a large serving bowl. Add chopped vegetables, beans, peas, olives, and cheese. Lightly toss to combine everything.
Pour dressing over pasta salad, and toss until everything is coated with dressing. Serve immediately, (or place in the fridge overnight and serve the next day for the best results!)
