Frozen vegetables? in Dermatitis Herpetiformis Posted July 8, 2018 · Report to Admin thank you for your comments. I am easing into the GAPS diet, which i believe is similar to Fasiano. I had both frozen vegetables and poultry seasoning yesterday (I simply forgot about the previous reaction) and I had no reaction. So I am even more puzzled. I do believe I should avoid seasonings and only use single spices, but I am still unsure about the frozen veggies.
