First off you need to boil the lentils, just follow the directions on the back of the bag.
While they are boiling bring a saute pan to medium heat with the 2 tablespoons of olive oil.
Throw all the ingredients (not the lentils though) into the sauce pan and let them saute a bit.
After about 3 minutes add the water to the sauce pan and cover it.
Let the veggies saute for another 5 minutes on LOW heat.
Once the lentils are at your desired softness, strain them, and add the contents of the pan.
Add Salt and Pepper to make it just right for you. Personally I prefer nothing but the ingredients I put in, but each person is different and I recommend letting guests season it to their individual liking.
