Grill chicken breasts.
Clean lettuce and dry and leave in bowl in refrigerator until ready to serve.
Add oil in jar – add anchovies (if you’re not crazy about them, leave them whole and put on top and whoever doesn’t like them can take them off), add crushed garlic, salt, vinegar, Worcestershire sauce and dry mustard. Just stir it all together. Add lemon juice.
When ready to serve, add the oil mixture to lettuce and toss well. Then add cheese and toss again.
Add croutons and chicken breasts that were sliced thin and diagonally.
