Bring a large pot of water to a boil. Salt generously and cook pasta according to box instructions for al dente. Drain, rinse with cold water and set aside.
In a large bowl, combine olive oil, lemon zest, lemon juice, garlic, salt and black pepper.
Trim chicken breasts of any excess fat and cut into thin strips. Place in bowl with marinade ingredients and set aside while preparing other recipe elements.
Preheat indoor or outdoor grill to medium to medium-high heat.
Add the chicken to the grill and cook about 1-2 minutes per side or until internal temperature reaches 165° F. Remove chicken from the grill and cut into bite-size pieces. Set aside.
for the dressing-
Add all dressing ingredients to a small blender and blend until smooth. (You can also whisk all ingredients in a small bowl if you don't have a blender.)
to assemble-
Place cooked pasta, romaine, grilled chicken, bacon, parmesan cheese shavings, and croutons in a large salad bowl. Drizzle with the caesar dressing and toss to combine well. Season with more freshly cracked black pepper, if desired and serve.
Notes
*You can skip the marinating and grilling of the chicken if you have precooked chicken on hand, either from leftovers, meal prep, or a store-bought rotisserie chicken. **If you are allergic to anchovies, you can leave these out of the recipe, but be sure to add salt (to taste). Anchovies have a high salt content, which is why I left salt out of the dressing ingredients. If you think you won’t like the taste, don’t worry – you can’t even tell they’re in there. They just give this dressing the essential umami, salty flavoring.
