Chickpeas and feta take care of the protein requirement, olive oil brings good fats, and whole-wheat couscous and broccoli make up the healthy carbohydrates.
Night before: Combine all the ingredients and refrigerate this salad in an airtight container.
This dish is delicious even if your cauliflower "steaks" are sliced less than perfectly. If you are cooking smaller pieces, simply reduce the cooking time by a few minutes. Use extra roasted vegetables later in the week for Easy Chickpea Curry.
