This is a very Spanish dish, very similar to a ratatouille but without aubergines.
You need:
3 large onions (into slices)
2 cloves of garlic (into thin slices)
1 red pepper (into cubes)
half a green pepper (into cubes)
5 courgettes - into thick slices
2 large tomatoes - into medium size cubes
a bay leave
salt
olive oil
Heat the olive oil on a frying pan over medium heat. Fry the onion. As soon as they are a bit golden add the peppers and garlic and let them fry for 5-8 minutes. Then add the tomatoes and fry them for another 3-4- minutes. Put the heat down to minimum and let it all soften for 10 more minutes. Then put it on a serving dish and reserve.
Add a touch more olive oil and fry the courgettes for 7-8 minutes. As soon as they are ready mix them with the onion and tomato mixture. Add salt and let it all bubble for 10 to 15 minutes over low heat.
If you get lots of liquid then increase the heat and let it evaporate for another 10 minutes or so.
Do not stir too much as you should keep the shapes of the vegetables.
You can eat this with grilled meat, grilled fish, a fried egg or just with crusty bread. The children also like it with grated cheese on top and then melted under the grill.
