Yes, I can eat avocados without becoming ill.
Aside from that, though, the peas (yes, I can eat black beans but not black-eye peas - I’m allergic to many legumes although thankfully not all) and corn in your recipe (including the tortilla chips), along with the tomatoes, are all things that would land me in the hospital, or worse. At which point… I’m not sure it’s “cowboy caviar” anymore.
Which is why I said that Mexican style cooking, along with Tex-Mex, are ruled out for me. Too many ways to kill me.
So… thank you for trying, and I’m sure other readers will thoroughly enjoy the recipe but I must politely decline that one.
(I do know one restaurateur who has cooked Mexican food for me that I can eat, but he did that to prove that when my spouse was chowing down on his Mexican favorites I didn’t have to just sit there and sip ice tea, he could safely feed me. Which was awful damn nice of him and why his is the only Mexican restaurant I eat at.)
