400 g crushed tomatoes, 1 tsp sugar, 1 bouillon cube, 50 ml hot water
Stir well and bring to a simmer.
Reduce the heat to low and let it cook for 20–30 minutes, stirring occasionally.

Let it simmer long enough for the excess liquid to reduce.
It should be slightly thick so it sits nicely between the lasagna layers without making the dish runny.
