Having just returned from Portugal I never really saw the Portuguese food there that we get here. I was looking forward to espetadas and trinchado but I never saw it on a menu.
Peri Peri Chicken is basically chicken braaid with some sauce that is not really peri peri, you get the peri peri on the side.
Roast pork with sauce over chips you get everywhere, but the best meals by far were the braaid sardines with chips and salad, those are tasty.
I also got 7 lamb chops and chips at a small restaurant in Loule, a small town on the Algarve for 6.50 Euros that were delicious. A bottle of Vinho Verde (Green wine) for 7.50 Euros made me miss the bus as I had two bottles.
