How to make best roasted fingerling potatoes
1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare Potatoes: In a medium-sized bowl, combine the potatoes, olive oil, a pinch of salt, and rosemary. Toss them together until the potatoes are evenly coated.
3. Arrange on Baking Tray: Line a baking tray with parchment paper. Place the potato mixture in a single layer on the tray.
4. Bake Potatoes: Bake the potatoes in the preheated oven for approximately 50 minutes. Remember to turn them halfway through the cooking time. Keep an eye on them, and they should become golden and tender.
5. Blanch the Beans: While the potatoes are baking, blanch the green beans. Bring a pan of water to a boil and add the beans. Cook them for 3-4 minutes, just until they become tender. Then, drain the beans and immediately refresh them under cold water. Drain them again.
6. Poach the Eggs: In a large pan, bring water to a simmer. Add 1 tablespoon of white wine vinegar. Gently crack the eggs into the simmering water. Poach them for 1-2 minutes for a soft consistency or longer if you prefer them more well-cooked.
7. Prepare Mustard Mayo: To create the mustard mayo, mix together whole egg mayonnaise, white wine vinegar, and mustard in a bowl. Stir until well combined.

8. Assemble the Dish: Place the baked potatoes on a serving platter. Top them with the blanched beans. Drizzle the prepared mustard mayo over the potatoes and beans.
9. Add Poached Eggs: Arrange the poached eggs down the center of the vegetables.
10. Serve: To serve, gently toss everything together at the table, allowing the eggs to break open and become part of the dressing. Enjoy your delicious dish!
Just a quick tip, when you are poaching the eggs, add 2 tablespoons of white vinegar to boiling water. It will help setting the eggs nicely! Works like a charm!
