Preheat the grill to medium-high heat.
Place all the vegetables in a grill pan.
Drizzle with olive oil and season with Italian seasoning, salt, and pepper.
Place veggies on the preheated grill.
Cook for 15-20 minutes, stirring occasionally, until vegetables are softened and cooked to your liking. I like my veggies a little on the crispier side so I cooked closer to 20 minutes.
Assemble your bowls by dividing the quinoa among four bowls.
Top with veggies and sauce.
Serve and enjoy!
