Instructions
- Step 1: Place 3 large eggs in a pot of cold water, bring to a boil, and cook for 10 minutes for hard-boiled eggs. Transfer to cold water, peel, and quarter.
- Step 2: In a medium pot, boil 8 oz trimmed green beans and 8 halved small new potatoes for 8 minutes until tender but firm. Drain and cool.
- Step 3: Whisk together 1 tbsp Dijon mustard, 2 tbsp red wine vinegar, 1 minced garlic clove, 1 tsp salt, and 1/2 tsp black pepper in a bowl. Slowly drizzle in 1/4 cup extra virgin olive oil while whisking to emulsify the dressing.
