Heat the oven to 425 degrees.
Place all the chopped up veggies (aside from the garlic) in a large bowl with the cooked chickpeas.
Mix the spices together in a small bowl.
Pour in the oil and soy sauce, stir, and then throw spice blend all over those veggies.
Mix until all the vegetables and shit are covered.
Put all of that on a large rimmed baking sheet and bake for 20 minutes.
Take it out of the oven, don’t burn yourself, add the garlic (optional), and stir it around.
Bake for another 15 minutes. The broccoli might look a little burnt at this point but that is the plan so chill the fuck out and take it out of the oven.
