Bring a medium-large pot of water to a boil. Add ½ tsp of salt then add the orzo. Cook until al dente, according to package instructions, approx. 8-10 minutes. Drain in a fine mesh colander and set aside.
While the orzo cooks, whisk pesto and vinegar together in a large mixing bowl.
If your pesto is extra-thick, feel free to add a drizzle or two of olive oil to the bowl as well.
Cut tomatoes in either halves or quarters and add to the mixing bowl along with drained chickpeas. Mix well to coat.
Add orzo, chopped basil, and a pinch of salt and pepper. Mix well and taste test. Add additional salt and pepper to taste as well as any additional basil, pesto, or vinegar you'd like to add to amp up the flavors to your liking.
NOTE: salt and pepper bring out the flavors of the pesto so don't skip this part! Start with a little of each, mix, and then increase until it's seasoned perfectly to your liking.
Serve warm, room temperature, or chill in the fridge before serving for a cold pasta salad vibe. It's great every which way! Chilled pasta salad tends to soak up sauces and dressing so simply add a little extra upon serving if desired. Enjoy!
