This is a vegetable gratin that uses low calorie soy milk. You don't need consomme cubes to make a tasty gratin.
I was wondering what would go nicely with a pasta dish in an oil-based sauce. I wanted to use up leftovers in my fridge too.
If you have time, microwave the dish you will use beforehand. This will make the surface brown faster in the oven.
