My brother moved to Norway recently from the Southwest US. He misses quality (and spicy) Mexican food every day.

I had awesome Mexican food in Ghana. Turns out it was some actual guy from Mexico that was living there and opened a restaurant. It helps that Mexico and all of West Africa have the same spice tolerance, but man, it was great. Cheese, as it turned out, was his logistical block, everything else was available or could get shipped in.

where can I find this muy authenico Mexican food?

Oh, there's more than just Greece that needs them. But I expect that in terms of climate, I'd rather go from Mexico to an island in the Ionian than Mexico to Helsinki.
