For several reasons, this isn’t totally paleo. Most Worcester sauce will have some soy sauce and/or sugar in it, and the seasoned salt we used (Lowry’s, of course), has some corn starch in it. Also, it’s likely that your store-bought plantain chips were fried, and probably in sunflower or canola oil.
If you want to make this more (if not perfectly) paleo, you can roast your own plantain chips in the oven; use 1 tsp himalayan pink salt, 1/4 tsp paprika, and 1/4 tsp pepper in place of the seasoned salt; and use coconut aminos or anchovy paste instead of the Worcester sauce.
