Pour pasta (from Suddenly Salad box) into 3-quart saucepan 2/3 full of boiling water. Gently boil uncovered 12 minutes, stirring occasionally. Drain pasta. Rinse with cold water; drain well.
In large bowl, mix seasoning & crouton blend (from Suddenly Salad box), 3 tablespoons olive oil and the lemon juice. Stir in cooked pasta. Cover; refrigerate until ready to serve. In small bowl, coat chicken tenders with mustard; set aside.
Heat gas or charcoal grill. Place chicken tenders on grill over medium-high heat. Cover grill; cook chicken tenders about 8 minutes, turning after 4 minutes, until chicken is no longer pink. Drizzle lettuce with olive oil. Place lettuce on grill, cut side down. Cook 1 to 2 minutes or just until light grill marks appear.
To serve, place pasta mixture on large serving platters. Top with chicken tenders. Arrange lettuce around edges of platter; top with cheese.
