I don't think it's unfair to point out that the general populace of Tenerife is a little more… solidly built than on the Spanish mainland. And now that we're getting familiar with the cuisine here, we understand why. Theirs is nourishing food, served in construction-worker portions. And if you're not out in the fields all day, or regularly exercising, all that protein has just one place to go.
Despite all the hiking we were doing, we definitely weren't losing any weight here in Tenerife. And that didn't surprise me, considering the hearty food, and the outsized portions in which they serve it. But we loved the island's cuisine, which is quite distinct from that of the Spanish mainland.
