Combine Light Mayonnaise, basil, lemon juice and garlic in small bowl; set aside.
Grill or broil chicken, turning once, 4 minutes or until chicken is thoroughly cooked.
Evenly spray cut-side of rolls with I Can't Believe It's Not Butter!® Spray Original and grill, pressing gently to sear, 1 minute or until rolls are toasted. Evenly spread rolls with basil mixture, then top with chicken, tomato, onion and lettuce.
Most home cooks make the mistake of placing cold poultry straight onto a hot grill, which causes the exterior to scorch before the center transfers heat evenly. Bringing cutlets to ambient temperature for 15 minutes prior to cooking prevents this thermal shock and promotes uniform searing.
Adapting for Dietary Restrictions
Replacing the standard mayonnaise with plant-based alternatives requires paying attention to fat ratios, as commercial vegan emulsions rely on starches that brown differently over direct heat. When modifying the whole wheat rolls for gluten-free diets, choose a brand containing xanthan gum to maintain structural integrity under the weight of the tomato and onion slices. Whole wheat grains contain robust protein structures that absorb moisture effectively, preventing the spread of aioli from making the base soggy during assembly.
Judging Doneness Without a Thermometer
Thin cutlets cook rapidly, usually requiring precisely 4 minutes per side under high heat. Piercing the thickest part of the meat allows observation of the juices; completely clear liquid indicates that the interior has reached 165 degrees Fahrenheit. Pressing the surface with a finger should yield firm resistance without feeling rigid or rubbery.
Building Flavor Profiles
Minced garlic releases allicin when crushed against a cutting board, creating a pungent base that mellows when combined with the acidity of lemon juice. Fresh basil contains volatile aromatic oils that degrade under prolonged heat, which is why incorporating the herbs into the cold spread preserves their distinct herbal notes.
