Instructions

1. Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Halve, peel and thinly slice onion. Halve grape tomatoes. Place bacon on a baking sheet; roast on top rack until crispy, 15-20 minutes.
2. Meanwhile, heat a large drizzle of oil in a large nonstick pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. If onion starts to brown too quickly, lower heat and add a splash of water. Add 1 tsp sugar and a splash of water; cook until onion has caramelized, 2-3 minutes more. Stir in ½ TBSP butter; season with salt and pepper. Turn off heat. Transfer to a paper-towel-lined plate. Wash out pan.
3. While onion cooks, in a large bowl, whisk together mustard, half the vinegar, 1 TBSP olive oil and ½ tsp sugar. Taste and season with salt and pepper. Stir in tomatoes; set aside to marinate.
4. In a medium bowl, whisk together crème fraîche and 2 TBSP water until mixture is smooth and has the consistency of heavy cream. If mixture is too thick, add a few more splashes of water. Whisk in eggs and ¼ tsp salt until thoroughly combined and mixture is pale yellow, 1-2 minutes.
5. Heat a small drizzle of oil and ½ TBSP butter in the pan used for onion over medium heat. Once butter begins to bubble, pour in egg mixture and cover pan with lid (or a baking sheet). Cook until omelet is just set and slightly puffed, 4-7 minutes. Check the underside often-it should be lightly golden when done. Add bacon, cheese and as much caramelized onion as you like to one side of omelet. Carefully fold opposite side of omelet over filling. Gently transfer omelet to a cutting board.
6. Toast bread until golden brown. Spread with 1 TBSP butter. Add mixed greens to bowl with marinated tomatoes; toss to combine. Cut omelet in half crosswise. Divide omelet, salad and toast between plates. Serve.
