01 - Preheat oven to 425°F for roasting the zucchini.
02 - Toss zucchini slices with 1 tbsp olive oil, oregano, salt, and pepper. Spread in a single layer on a baking sheet.
03 - Roast zucchini for 20-25 minutes, flipping halfway through, until golden edges develop and pieces are tender.
04 - Heat 2 tbsp olive oil in a medium saucepan over medium heat. Add onion and cook 3 minutes until softened. Stir in garlic and cook 1 minute until fragrant.
05 - Add rinsed brown rice to the saucepan, stirring constantly for 1-2 minutes to toast the grains and coat with oil.
06 - Pour in vegetable broth, salt, and pepper. Bring to a boil, then reduce heat to low, cover tightly, and simmer 35-40 minutes until rice is tender and liquid is fully absorbed.
07 - Fluff rice with a fork. Gently fold in roasted zucchini, parsley, dill or basil, lemon zest, and lemon juice. Adjust seasoning with additional salt and pepper if needed.
08 - Transfer to a serving dish and serve warm. Garnish with additional fresh herbs if desired.
