Boil the pasta to al dente according to the package instructions (around 7 minutes). Add the frozen peas into the boiling pasta just before draining it. Then run some cool water over the peas and pasta.
Meanwhile, drain and rinse the chickpeas before adding them to a large mixing bowl. Use a fork to mash them. Dice the onions and celery, then add them to the bowl.
Add the dressing ingredients to a small mixing bowl. (vegan mayo, dijon mustard, lemon juice, old bay, salt, pepper, paprika, black salt) Whisk them together.
Add the peas, pasta, dressing, and fresh dill to the large bowl. Stir everything together until it’s well combined.
Cover and chill the pasta in the refrigerator for 1 hour. Give it one more good stir to redistribute the dressing. Add more fresh dill for garnish and enjoy!
