Steps
1. Start by toasting the slice of bread until golden brown.
2. In a small skillet, melt the butter over medium heat and add the toasted bread, allowing it to soak up the butter for 1 minute.
3. Place the milk cheese on top of the bread and let it melt slightly (about 1-2 minutes).
4. While the cheese is melting, slice the avocado and set aside.
5. In a bowl, mix the lettuce with olive oil, lemon juice, salt, and pepper.
6. Once the cheese has melted, top the toast with sliced avocado.
7. Serve the avocado toast alongside the lettuce salad.
