Put the bacon in a pan, and over medium heat, I fried it until it got a golden colour. Remove the fried bacon on a paper towel, and let it cool.
Next is the romaine lettuce, which I cleave the leaves into pieces and washed each one then I simply cut them into pieces. The avocado, which after removing it with a spoon from the peel, I cut into slices. Cut the Greek feta cheese into not too big cubes.
Cut the cherry tomatoes according to their size, the smallest in two, or if they are bigger in four. Boiled the eggs for about 10 minutes, until I got hard boiled eggs. I cleaned it and let it cool, after which I cut them into pieces.
Put all the ingredients one by one, as you cut them, in a bowl. Season with salt, pepper and oregano. Make a dressing with olive oil, mustard, lemon juice and balsamic vinegar, and pour over tha salad.
