Fry the spelt in a large pan for around 2-3 minutes on a medium heat (no oil). Watch out it doesn’t burn! Just as it starts to release its aroma and turn brown, add the stock and stir well. Turn the heat off and let the spelt sit for 20 minutes, stirring now and then. If the pan cools down completely, let it simmer on a low heat instead.
Dice the zucchini, onion and all other veg into tiny pieces.
After 20 minutes, add the zucchini, onion and any other veg into the spelt, along with the tomato puree and tomato paste.
Also add salt, pepper and basil. Taste test, and if the tomato wasn't particularly sweet, add a tsp sugar to offset it. Let it all simmer on a low-medium heat for around 10 mins.
If cooking for fussy children who don't like to see things like zucchini in their food, then you can use a handblender here to blend the veggies together.
Prep time next: Add ⅓ of the spelt/veg mix to an oven tray. Layer lasagna sheets over it, and on top of that add ⅓ bechamel sauce, using a spoon to spread it over the sheets . Add the next ⅓ spelt/veg mix, more lasagna sheets and another ⅓ bechamel sauce. Finally add the rest of the veg mix and another layer of bechamel sauce (no more lasagna sheets). On the top layer, sprinkle the grated cheese. Ready!
Into the oven for 35 minutes on 200°C/390°F, or until a deep golden brown. Best lasagna ever.
