Wash and pat dry chicken breast halves. Place chicken in a plastic baggie along with sriracha chili sauce and oil, squishing to evenly disperse marinade. Refrigerate and marinade 4 hours.
Remove marinated breast and pat dry. Sprinkle with salt. Place breasts under broiler or on grill, cooking until no longer pink in center and juices run clear, about 5-10 minutes on each side. Let cool then cut into diagonal ¼ inch slices; set aside. This step can be done early in the day or even the day before.
Divide between 2 plates the mixed greens, tomato halves and red onion. Place on top one cut-up breast per plate then top with bacon and sprinkle with Parmesan cheese.
