Eating almost exclusively at home and an food allergy dedicated restaurant. After still getting headaches I asked the owner and he pointed out the pepperoni. Tested independently with deli meat and bacon. Best advice is to do an elimination diet. It improved for me then it was years of trial and error. I basically just eat meat, rice, milk, butter, and broccoli now but not wanting to take a drill to my forehead is great.
