feijoada - a kind of bean stew with several meats and sausages...hearty and yummy.
I'd tell you how it's made but I doubt you'd be able to get the right ingredients for it.
Not healthy though
Bacalhau com Grão - Cod with Chick Peas. This one is easy if you can get a hand on salted cod. Basically just boil the ready prepared salted cod (having removed any bones first), and separately boil chick peas and potatoes, and separately the green veg of your choice (I use broccoli), and serve, covered in lashings of minced onion and parsley, and copious amounts of olive oil and vinegar. Delicious. I imagine this recipe is a bit healthier.
These are both Portuguese. Of course...what else?
