Instructions
- 1Dice the onion into small pieces. Heat a large nonstick skillet over medium-high heat and spray lightly with cooking oil. Add the onion and cook 3–4 minutes, stirring occasionally, until translucent.
- 2Dice the tomato and add to the pan. Cook 2–3 minutes, stirring, until the tomato begins to soften and release its juices.
- 3Add the ground beef to the skillet, breaking it apart with a wooden spoon as it cooks over medium-high heat. Cook 5–7 minutes, stirring frequently, until no longer pink and the beef is fully browned. Drain excess fat if needed.
- 4Stir in the taco seasoning packet along with the water called for on the packet. Simmer over medium heat 2–3 minutes until the mixture thickens slightly and coats the beef evenly. Transfer to a bowl and let cool slightly.
- 5Cut the avocado in half, scoop the flesh into a small bowl, and mash with a fork. Stir in fresh lemon juice and a pinch of salt until smooth.
- 6Assemble four sandwiches: spread mashed avocado on the inside of each bread slice, layer spinach leaves, divide the taco beef evenly (about ¼ cup per sandwich), add diced tomato, mozzarella, taco sauce, and a dollop of sour cream. Top with the second bread slice.
- 7Lightly spray both sides of each sandwich with cooking oil. Working in batches if needed, place sandwiches in the skillet over medium-high heat and cook 3–4 minutes on the first side until golden brown and crispy.
- 8Flip each sandwich carefully and cook the second side 3–4 minutes until golden brown and the cheese has melted completely. Divide the sandwiches evenly among four plates and serve immediately.
