A healthy burger without a bun

Ingredients:

• 2 slices of bacon
• 1 head of Iceberg lettuce (1-1.3 kg.)
• 280 g of ground beef with 15% fat content
• 2 tbsp blue cheese dressing with cheese chunks
• 2 tbsp red onion, diced

Preparation:

1. In a medium cast iron skillet, cook the bacon over medium heat, turning once, until crisp, about 8 minutes. Transfer to a paper towel-lined plate to drain. Drain any excess rendered fat from the skillet, reserving enough to coat the bottom.
2. Cut 4 rounded lettuce slices (10-12 cm) from the top and three sides of the iceberg lettuce head to create bun-shaped pieces; place on a platter.
3. Form the ground beef into 2 patties, each approximately 10 cm wide and 2 cm thick, and season both sides with salt and black pepper. Place the skillet with the rendered fat over high heat, add the patties, and cook for 3 minutes; flip and cook for another 3 minutes for medium-rare.
4. Place one lettuce slice, cut side up, on each of two plates and top with a burger. Spoon 1 tablespoon of dressing over each burger and add 1 tablespoon of onion. Crumble 1 slice of bacon over each burger and top with the remaining lettuce slices.
