Recipe Questions & Answers

What vegetables work best for roasting?

Bell peppers, cauliflower, broccoli, zucchini, carrots, and cherry tomatoes roast beautifully. They become tender and lightly caramelized while maintaining their texture.

Can I prepare this ahead?

Yes! Roast vegetables and cook rice in advance. Store separately and assemble when ready to eat. The herb sauce keeps for 3-4 days refrigerated.

How do I add more protein?

Chickpeas, tofu, or tempeh roast well alongside vegetables. You could also top with grilled chicken, hard-boiled eggs, or hemp seeds.

What's the best way to reheat?

Warm vegetables and rice gently in a 350°F oven or skillet. Avoid microwaving to prevent sogginess. Fresh sauce adds brightness back to reheated portions.

Can I use different herbs?

Absolutely. Try dill, tarragon, or mint instead of basil. Adjust quantities to taste. The sauce base of olive oil and lemon juice remains the same.
