1 1/2cupslentils, green or brown (rinsed and drained
1small Yukon potato, diced
Instructions
In a large 4-5 quart stockpot or dutch oven, heat the olive oil and butter over medium heat until the butter starts to foam. Add the pancetta and bacon and cook for about 7 minutes or until the bacon reaches your desired crispiness. Add the garlic, carrots, celery, onions and mushroom and cook the mixture for 10 to 12 minutes or until the vegetables are tender and lightly browned.
Add 4 cups of the chicken stock to the pot and then stir in the tomato sauce, fish sauce (if using), bay leaves, salt, thyme, oregano, red pepper flakes, and black pepper. Add the lentils and potatoes, increase the heat to medium-high and bring the soup to a boil.
Partially cover the pot and reduce the heat to a simmer. Cook the soup for about 45 minutes.
Add more chicken stock if the soup becomes too thick. Taste the soup and add salt if necessary. Remove the bay leaves and serve.
Notes
To make the soup vegetarian, exclude the pancetta and use a vegetarian bacon (such as tempeh bacon or other) in place of the bacon. Exclude the fish sauce and sub vegetable stock for the chicken stock. The vegetarian version is quite delicious in its own right. For vegan, use all olive oil instead of butter.
