**🍽️ Classic {food_display} Recipe**

**📋 Ingredients (Serves 4):**
• 2 lbs fresh {food_display.lower()} (main ingredient)
• 3 tbsp extra virgin olive oil
• 1 large yellow onion, finely chopped
• 3 cloves garlic, minced
• 2 tsp sea salt (adjust to taste)
• 1 tsp freshly ground black pepper
• 2 tbsp fresh herbs (parsley, thyme, or rosemary)
• 1 lemon (zested and juiced)
• 2 tbsp butter (for finishing)
• Fresh vegetables for sides (carrots, broccoli, or green beans)

**👨‍🍳 Detailed Instructions:**

**Prep Work (10 minutes):**
1. **Prepare ingredients:** Wash all vegetables, mince garlic, chop onions, and measure spices
2. **Season main ingredient:** Pat dry and season generously with salt and pepper, let rest 15 minutes
3. **Preheat equipment:** Heat oven to 375°F (190°C) or prepare stovetop on medium-high heat

**Cooking Process (25-30 minutes):**
4. **Sear for flavor:** Heat olive oil in heavy pan, sear main ingredient until golden (3-4 minutes per side)
5. **Build the base:** Add onions and garlic, cook until fragrant and translucent (5 minutes)
6. **Add aromatics:** Incorporate fresh herbs, lemon zest, and any liquid components
7. **Slow cooking:** Reduce heat to medium-low, cover, and cook until tender (15-20 minutes)
8. **Final touches:** Add butter, lemon juice, and adjust seasoning to taste

**Plating & Presentation:**
9. **Rest the dish:** Let rest 5 minutes before serving to allow flavors to meld
10. **Garnish beautifully:** Top with fresh herbs, a drizzle of quality olive oil, and lemon wedges

**💡 Classic Cooking Tips:**
• **Quality ingredients:** Use the freshest, highest-quality ingredients you can find
• **Patience is key:** Don't rush the cooking process - good food takes time
• **Taste as you go:** Adjust seasoning throughout the cooking process
• **Temperature control:** Use a meat thermometer for perfect doneness
• **Rest time:** Always let proteins rest before serving to retain juices

**🍷 Perfect Pairings:**
• **Wine:** Medium-bodied red wine or crisp white wine
• **Sides:** Roasted seasonal vegetables, garlic mashed potatoes, or wild rice
• **Bread:** Crusty artisan bread with herb butter

**⏱️ Timing Guide:**
• **Prep Time:** 15 minutes
• **Cook Time:** 30 minutes
• **Total Time:** 45 minutes
• **Difficulty:** Intermediate

**🔥 Chef's Secret:**
The key to this classic recipe is building layers of flavor. Start with a good sear, add aromatics gradually, and finish with fresh herbs and acid for brightness."""

**🌱 Healthy {food_display} Recipe**

**📋 Nutritious Ingredients (Serves 4):**
• 2 lbs organic {food_display.lower()} (hormone-free, sustainable)
• 2 tbsp avocado oil (high smoke point, healthy fats)
• 1 cup rainbow vegetables (bell peppers, carrots, zucchini)
• 2 cups leafy greens (spinach, kale, or arugula)
• 3 cloves garlic, minced (immune-boosting)
• 1 tbsp fresh ginger, grated (anti-inflammatory)
• 2 tbsp coconut aminos (low-sodium soy sauce alternative)
• 1 tbsp apple cider vinegar (probiotic benefits)
• 2 tbsp pumpkin seeds (healthy fats and protein)
• 1 avocado, sliced (omega-3 fatty acids)
• Fresh herbs: cilantro, parsley, basil

**👩‍⚕️ Healthy Cooking Method:**

**Nutrient Preservation (10 minutes):**
1. **Gentle preparation:** Use sharp knives to minimize cell damage, preserving nutrients
2. **Smart seasoning:** Use herbs and spices instead of excess salt for flavor
3. **Preserve enzymes:** Don't over-wash vegetables; light rinse maintains nutrients

**Heart-Healthy Cooking (20-25 minutes):**
4. **Oil selection:** Use avocado oil for high-heat cooking, olive oil for finishing
5. **Steam-sauté method:** Use minimal oil with splash of water for steam-cooking effect
6. **Low-heat approach:** Cook at medium heat to preserve delicate nutrients
7. **Quick cooking:** Minimize cooking time to retain vitamins and minerals
8. **Add greens last:** Incorporate leafy greens in final 2 minutes to preserve folate

**Superfood Finishing:**
9. **Raw additions:** Top with raw avocado, pumpkin seeds, and fresh herbs
10. **Probiotic boost:** Drizzle with apple cider vinegar and a touch of olive oil
