Whisk together the olive oil, white wine vinegar, honey Dijon mustard, red onion, sea salt, black pepper, and lemon juice in a microwave-safe bowl.
Cook the oil mixture in the microwave until hot and almost boiling, about 1 1/2 to 2 minutes. Gradually whisk in the sugar until the dressing is thick and creamy.
While the dressing is still warm, serve it alongside sliced bacon for an added crunch.
