Ingredients

• For the Salad
• 2 mackerel fillets, about 5 oz / 150g each
• 2 large eggs
• 1 medium avocado, sliced
• 2 cups / 225 g green beans, trimmed
• 4 cups / 120 g mixed lettuce such as lamb lettuce, arugula, or kale
• 1 tbsp / 15 ml ghee or butter
• ¼ tsp / 1.5 g salt, or more to taste
• Freshly ground black pepper
• For the Lemon & Mustard Dressing
• 2 tbsp / 30 ml extra virgin olive oil
• 1 tsp / 5 ml Dijon mustard
• 2 tbsp / 30 ml fresh lemon juice

Instructions

1. Place the eggs in a small saucepan and cover with cold water. Bring to a boil, then reduce the heat to a simmer and cook for 10 minutes for hard-boiled. Immediately transfer to a bowl of ice water to chill.
2. While the eggs cook, bring a separate pot of salted water to a boil. Add the green beans and cook for 4-5 minutes until tender-crisp. Drain and set aside.
3. Prepare the dressing by combining the extra virgin olive oil, Dijon mustard, and lemon juice in a small bowl or jar. Whisk or shake until well emulsified. Season with a pinch of salt and pepper.
4. Pat the mackerel fillets completely dry with a paper towel. Make a few shallow cuts into the skin side, being careful not to slice all the way through. Season both sides generously with salt and pepper.
5. Heat the ghee in a non-stick skillet over medium-high heat. Carefully place the mackerel fillets skin-side down. Press gently with a spatula for 20 seconds to ensure the skin makes full contact with the pan. Cook for 3-4 minutes, until the skin is golden brown and crispy. Flip and cook for another 1-2 minutes until the fish is opaque and cooked through.
6. To assemble, peel and quarter the chilled eggs. In a large serving bowl, combine the mixed lettuce and cooked green beans. Top with the quartered eggs, sliced avocado, and the crispy mackerel fillets (either whole or flaked). Drizzle generously with the dressing and serve immediately.

Pro Tips

• Ensure your mackerel fillets are completely dry before seasoning and placing them in the pan. This is the secret to achieving that incredibly crispy, non-stick skin.
• For perfectly crisp-tender green beans, plunge them into an ice bath immediately after boiling. This stops the cooking process and preserves their vibrant green color.
• Swap the mackerel for salmon, trout, or even canned tuna in a pinch for a different flavor profile.
• Make a double batch of the dressing! It stores well in an airtight container in the fridge for up to a week and is fantastic on other salads or grilled vegetables.
