I am from Panama! Since my family doesn't live in Panama or in a large latino community, we rely on GOYA food brand. The spices and seasonings are the closet we can get to authentic latino flavor. For lentils add Goya Adobo seasoning, tomato paste, and/or recaito(green) even sazon paquetes/packets of achiote for color or w/o achiote for no yellow/orange color. I'm telling you, this will remove the bland and add the flavor you want.
We thought this was ok, but found it to be a tremendous amount of work. After over an hour the lentils had still not come to a boil so we cranked them up and decided that we didn't care if they split. This had ok flavor, but was sort of bland. We ate it with flat bread.
Very easy to make. Very good flavour. Lentils can be boring and bland, but this simple recipe is so good. Be careful not to add too much salt with the stock cubes as they are salty already. I also tried it with carrots replacing the peppers and it had a similar sweetness. Great as an accompaniment with fish - I had swordfish loins and a small salad garnish. Great!
