This grain bowl is a choose-your-own-adventure delight. Sub in any grain, protein, or leafy green you have on hand—no matter what you choose, the deliciously easy sesame-based dressing will tie it all together. You'll have enough for at least two lunches plus leftovers. Make a double batch of the dressing to have enough for a full week of easy lunches. For a vegan version of the dish, skip the egg and up your protein with a larger serving of the broccoli/chickpea mixture.
