Season the bread with salt, pepper, and oregano in a bowl.
Sprinkle the bread with olive oil to coat it thoroughly (about 2 tbsp, but add more oil if needed).
Put baking paper on a baking dish, and spread the bread pieces evenly.
Bake in an oven at 400 F (200 C) for about 10 minutes (or until golden and crispy).
Take it out of the oven and let it cool.
Homemade Caesar Dressing prep.
Add minced garlic, 2 tablespoon olive oil, ½ cup plain kefir, ½ freshly squeezed lemon, 1 tbs sour cream, 1 teaspoon dijon mustard, 2 teaspoon grated parmesan cheese, and pepper to a bowl and mix with a wooden spoon.
If you have a food processor, mix everything in a food processor.
Taste the dressing and if it is not salty enough, add more salt.
Transfer to a glass jar with a lid, and let it sit in the fridge until ready to put over salad.
Chicken Prep.
Prepare about 1.2 lb of chicken breasts (about 2 larger pieces).
Cut them half lengthwise, and then cut each slice into two - to end up with eight pieces total.
Transfer the chicken breasts into a glass container with a lid—season with olive oil, salt, pepper, oregano, and thyme.
Close the lid and shake the container to coat evenly. Set aside to rest.
Oil the cast-iron skillet and heat it up on low heat. Add as much oil as will work for your cast-iron skillet. I usually start with 1 teaspoon of oil and make sure to have even coverage, and then wipe away any excess with a paper towel.
Cook the chicken breasts until golden on both sides. Set aside.
Assemble the salad.
Get enough butter lettuce (or romaine lettuce) for a medium-size plate, and cut it into bite-size pieces.
