Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). In a large bowl, toss 8 oz cubed tempeh and 4 cups cauliflower florets with 3 tbsp olive oil, 1 tsp smoked paprika, 1 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper until evenly coated.
  2. Step 2: Spread the tempeh and cauliflower on a large sheet pan in a single layer. Roast for 25-30 minutes, turning halfway through, until tempeh is golden and cauliflower edges are lightly browned.
  3. Step 3: Meanwhile, whisk together 3 tbsp tahini, 2 tbsp fresh lemon juice, 2 tbsp water, and 1/2 tsp ground cumin in a small bowl until smooth and creamy.
  4. Step 4: Drizzle the tahini-lemon sauce over the roasted tempeh and cauliflower, then garnish with 2 tbsp chopped fresh parsley before serving warm.
