This is no "great chieftan of the pudding race". But perhaps it's what you seek?

Ingredients

1 tablespoon vegetable oil
1 medium onion, finely chopped
1 small carrot, finely chopped
5 fresh mushrooms, finely chopped
1 cup vegetable broth
1/3 cup dry red lentils
2 tablespoons canned kidney beans - drained, rinsed, and mashed
3 tablespoons ground peanuts
2 tablespoons ground hazelnuts
1 tablespoon soy sauce
1 tablespoon lemon juice
1 1/2 teaspoons dried thyme
1 teaspoon dried rosemary
1 pinch ground cayenne pepper
1 1/2 teaspoons mixed spice
1 egg, beaten
1 1/3 cups steel cut oats

Directions

Heat the vegetable oil in a saucepan over medium heat, and saute the onion 5 minutes, until tender. Mix in carrot and mushrooms, and continue cooking 5 minutes. Stir in broth, lentils, kidney beans, peanuts, hazelnuts, soy sauce, and lemon juice. Season with thyme, rosemary, cayenne pepper, and mixed spice. Bring to a boil, reduce heat to low, and simmer 10 minutes. Stir in oats, cover, and simmer 20 minutes.
Preheat oven to 375 degrees F (190 degrees C). Lightly grease a 5x9 inch baking pan.
Stir the egg into the saucepan. Transfer the mixture to the prepared baking pan. Bake 30 minutes, until firm.
