Combine oil, garlic, salt, and pepper and allow it to sit 30 minutes. If you have a muddler, muddle the garlic a bit to impart flavor quicker.
Preheat oven to 400 degrees.
Prep your chosen vegetables, cutting each type of vegetable in similar sizes to allow for even cooking (leave mushrooms and tomatoes whole if using).
You want to time the vegetables adding those that cook quicker, later.
Carrots 30 minutes
Onions 25-30 minutes
Zucchini 20 minutes
Peppers 20 minutes
Asparagus depending on thickness 15-20 minutes
Grape tomatoes 15 minutes
Add those that take longer to cook first.
Be sure to allow space between vegetables, allowing them to roast instead of steam (use two baking sheets if necessary)
Toss vegetables as you add them with just a bit of the oil and season with additional salt and pepper.
Reserve at least 1 TBS of the seasoned oil to use on the rice.
You can also sprinkle with paprika, onion powder, and garlic powder if you wish as well.
While vegetable roast, prepare rice according to package directions (using vegetable broth in place of the water for better flavor).
Once rice is finished cooking, toss it with 1 TBS of the seasoned oil (or more if it's left), then place the roasted vegetables over-top of the rice. Pour any pan juices over the rice for extra flavor.
