Fun with Tortillas, Lentils, and Sausage

Yesterday afternoon Hannah and I's neighbor/hostel caretaker came over and taught us how to make tortillas from Maseca flour. As it turns out, you pretty much just mix the flour with water until it reaches a pretty basic baking consistency, then roll some into a ball, smack it into a flat round pancake, and put it onto a hot surface such as our lovely frying pan. Then you watch it and flip it when it starts to burn and it's done when it's not squishy anymore. Voila! Tortillas. We'll be old pros by next week.
Also yesterday I wrote down two different recipes for lentil soup. I sort of combined them to make a simplified lentil & sausage soup over rice that turned out delicious. Also fantastic, we bought the necessary ingredients for the equivalent of less than sixteen US dollars. We're having it for lunch and dinner today, and probably lunch again tomorrow because I made so much.
Thanks to my sister for the idea of cooking lentils and sausage! The only tough thing about it was that the sausage we've been buying is really hard to tell when it's cooked through, because it remains pink even when cooked. It's either pink and raw, a subtly different pink and cooked, or burnt. Any tips?
