Homemade Ranch: add all the ingredients into a bowl and mix well to combine. Set aside to let the ingredients marinade.
Hot Honey: in a small pot, add all the ingredients and bring to a simmer. Let the honey melt, mix well to combine and wait for the hot honey to slightly thickened. Set aside to cool.
Breaded chicken: Slice your chicken breast into 2 pieces length-wise. While working with 1 piece at a time, cover the chicken with a piece of plastic wrap and using a meat tenderiser, flatten out the chicken into a thin even piece. Repeat with the other piece. Season the chicken with salt and pepp.
Add your breadcrumbs onto a plate and mix in the parsley, onion powder and garlic powder. Prepare your breading station. Working with 1 piece of chicken at a time, place the chicken into your flour and cover it well. Transfer the chicken to your beaten eggs and cover it well. Transfer the chicken to your seasoned breadcrumbs and press it in well. Repeat with the 2nd piece.
Bring a pot of oil to frying temperature (180C/ 350F). Carefully drop in 1 piece of breaded chicken at a time and fry for 4-6 minutes, depending on the thickness of the chicken and flipping halfway, or until golden brown. Place on a wire rack to drain.
Assemble: On 1 piece of toasted bread, spread on a layer of the homemade ranch, then top with a piece of chicken. Brush on the hot honey, and top with lettuce. Close the sandwich. Enjoy!
