Place the bacon in a large, deep skillet, and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain the bacon slices on a paper towel-lined plate; crumble and set aside. Cook onion in bacon grease - drain.
Combine the olive oil, red wine vinegar, white sugar, salt, garlic, and Gorgonzola cheese in a blender; blend until smooth. Pour the dressing into a small saucepan over medium-low heat and warm gently.
Toss the baby greens, onions, almonds, and crumbled bacon together in a salad bowl; drizzle dressing over salad and toss to coat. Serve immediately.
