Heat a little oil in a large pan, and brown your ground beef.

In a separate pan, warm up the refried beans.

When the meat is cooked, stir in the taco seasoning and a cup of water. Simmer until the water has evaporated. Set aside.

Meanwhile, dice up tomatoes and avocado, grate cheese, and clean and chop the lettuce.

To make your dressing, whisk the olive oil into the lemon juice.

When everything is ready, set up a little production line, including the remaining ingredients, so everyone can build their salad as they like.
