Take a large bowl and put mayonnaise in. Then add oil.
Afterwards, take a lemon and cut it in half. Take half of the lemon and squeeze the juice into the bowl. Then shake your salt and pepper for about 5 seconds into the bowl. Don't forget to crush your cloves of garlic and put them in the salad.
Then, take your lettuce, cut it, put in the bowl, and mix everything. Then add the cheese on top with croutons and you're done.
