Line a baking sheet with parchment paper and preheat oven to 425℉. Place frozen tenders on baking sheet and bake for 7 minutes. Allow tenders to cool then cut into bite-sized pieces (each tender should yield about 4 bites). Turn heat on oven up to 450℉.
In a medium sized bowl toss together the Rebellyous tenders and 1/2 cup of BBQ sauce. Mix well to coat each piece. Set aside.
In a small bowl, whisk together the remaining 1/2 cup of BBQ sauce and the crushed tomatoes. Then brush that mixture onto the prepared pizza crust.
Evenly sprinkle vegan mozzarella shreds around pizza then top with BBQ Rebellyous tender pieces and sliced red onion. Bake until the crust is browned and pizza is cooked through, about 15 minutes. Cool for 10 minutes and top with ranch dressing and cilantro, then cut and serve. Enjoy!
