Follow these steps to create your Crispy Chicken Caesar Sandwich:

1. Prepare Chicken: Flatten the chicken breasts to ensure even cooking by pounding them to about ½ inch thickness.
2. Season: Season both sides of the chicken breasts with salt, pepper, garlic powder, and paprika.
3. Set up Breading Station: In three separate bowls, prepare one with flour, one with beaten eggs, and one with bread crumbs.
4. Bread Chicken: Dredge each chicken breast in flour, then dip in the beaten eggs, and finally coat with bread crumbs. Ensure they are evenly coated for maximum crispiness.
5. Heat Oil: In a deep skillet, heat around ½ inch of olive oil over medium-high heat until shimmering.
6. Fry Chicken: Carefully place the breaded chicken in the hot oil. Fry for 4-5 minutes per side, or until golden brown and cooked through. Check doneness with a meat thermometer (165°F is recommended).
7. Drain: Remove the chicken from the skillet and place it on a paper towel-lined plate to absorb excess oil.
8. Assemble Sandwiches: On each toasted bun, layer romaine lettuce, a generous amount of Caesar dressing, a piece of crispy chicken, and sprinkle with grated Parmesan cheese.
9. Top It Off: Place the top bun on and gently press down to secure all ingredients.
10. Serve Immediately: For best results, serve the sandwiches immediately while they are warm and crispy.
