Steps

1. Slice the tomato into pieces about 1cm thick. Wash the lettuce, pat it dry, and tear it into bite-sized pieces.

2. Heat olive oil (to taste) in a frying pan over medium heat. Crack 1 egg into the hot pan and cook. In the same pan, cook 3 slices of bacon over medium heat. Once the bacon is browned, flip it and remove once cooked. For the fried egg, once the whites start to set, flip it and cook both sides. Adjust the cooking to your preference, and remove once cooked. [Key Tip!] When packing for lunch, ensure the yolk is fully cooked. Cooking both sides makes the egg less likely to collapse when assembled.

3. Line the toaster tray with non-stick aluminum foil and toast 2 slices of bread until golden brown.
   🕒 03:43
4. Mix 5g of salted butter (at room temperature) with a little mustard. [Key Tip!] Omit the mustard if serving to children.
   🕒 04:03
5. Mix 1 tsp of ketchup and 1 tsp of mayonnaise.

6. Spread the prepared mustard-butter mixture on the untoasted side of one slice of bread. [Key Tip!] Applying a layer of fat to the bread prevents the moisture from other ingredients from soaking into it. [05:13] Place the cooked 3 slices of bacon on top of the bread with butter. [05:30] Place the cooked 1 egg on top of the bacon. Position it so the yolk is in the center when cut. Fold in any overflowing parts. [05:47] Generously spread the prepared ketchup-mayonnaise sauce over the egg. [05:54] Place the sliced 1 tomato slice in the center on top of the sauce. [05:58] Arrange the torn 1 lettuce leaf on top of the tomato, adjusting the amount as desired. [06:07] Place the other slice of bread on top of the fillings and press down gently. [06:12] Place the sandwich in the center of a piece of parchment paper cut to a length that will wrap around it, with the cut side facing down. [06:27] Bring the top edge of the parchment paper to the sandwich and wrap it tightly, folding it over about 3 times. [06:56] Once wrapped, rotate the sandwich and fold the sides of the parchment paper down along the edges of the bread. Tuck the ends underneath. Repeat on the other side. [Key Tip!] Wrap the parchment paper tightly. If this is difficult, you can use plastic wrap and wrap it tightly.

7. Let the wrapped sandwich rest for about 5 minutes. [07:55] Once rested, place it with the folded seam facing down and cut it in half.
