Basic Brown Rice Pilaf

Hiding vegetables in Partner's food has been a weekly challenge. The carrots, peppers and celery are not indistinguishable in this brown rice pilaf, but they are chopped finely enough, I wonder if his time is worth picking out the small, colorful bits of nutrients...well- it must be (or he must be rather bored at work) because his containers routinely come home entirely void of grilled chicken and brown rice, but conspicuously dotted with finely chopped vegetables.
This is a staple recipe for me, easy and healthy as can be. I take 1/2c for a 10am meal with chicken breast and Partner takes a 2 1-cup measures a day with either chicken or other lean meat. Make a bunch, portion it and freeze it for the week.
