Ratatouille calzones

Last week I told Joao that for the weekend I wanted to make something different for lunch: I was not in the mood for pasta or for the good old rice and beans combo, and I definitely wanted to try my hands at a new recipe.

Going through the vegetables in my fridge I found one eggplant, one zucchini, a couple of carrots and that was it: not much to choose from. So I kept the carrots for some other time and used the eggplant and the zucchini to make a sort of ratatouille, adding tomato paste and olive to make the mixture more interesting. Mixed with cheese it became the filling for these calzones and I bring you this recipe with a very proud smile: the calzones turned out so good!

Apparently going through the crisper drawer might be a good creative exercise. :D

The recipe yields 8 large calzones, which is too much for the both of us for one meal, so I froze the remaining calzones and we ate them for dinner yesterday. If you want to do the same, just wait for the calzones to cool completely, wrap in foil and place them in a plastic bag, sealing well. Once the calzones are thawed, 10 minutes in a hot oven are enough to make them delicious again.

Ratatouille calzones
own recipe

Dough:
2 teaspoons dried yeast
½ teaspoon granulated sugar
1 ¼ cups (300ml) lukewarm water
2 tablespoons extra-virgin olive oil
3 cups (420g) all purpose flour
1 ¼ teaspoons table salt

Filling:
1 ½ tablespoons olive oil
½ small onion, finely diced
1 large garlic clove, minced
1 medium zucchini (240g), in 1cm-cubes
1 medium eggplant (300g), in 1cm-cubes
1 bay leaf
salt and freshly ground black pepper
½ tablespoon tomato paste
1 tablespoon dry white wine
10 large black olives, pitted and finely chopped
1 ½ cups (150g) coarsely grated yellow mozzarella*
3 tablespoons coarsely grated parmesan
2 teaspoons dried oregano

After assembling the calzones:
olive oil, for brushing
finely grated parmesan, for sprinkling over the calzones

Start with the dough: in the bowl of an electric mixer fitted with the dough hook, mix the yeast, sugar and water with a fork. Set aside until foamy, about 5 minutes. Add the olive oil, flour and salt and mix for 6-8 minutes or until a soft and elastic dough forms. Shape dough into a ball and transfer to a lightly oiled bowl. Cover with plastic wrap and set aside to proof in a warm place for about 1 hour or until doubled in size – mine proved for 90 minutes.

In the meantime, make the filling: heat a large nonstick frying pan over medium heat. Add the onion and cook stirring occasionally until tender and translucent. Add the garlic and cook for 1 minute or until fragrant – do not let it burn or it will get bitter. Stir in zucchini, eggplant and bay leaf, season with salt and pepper. Cook for 5-7 minutes or until vegetables are softer. Stir in the tomato paste and cook for 2 minutes – it is important to cook it thoroughly to avoid the raw tomato aftertaste. Add the wine and cook for 1 minute, then stir in the olives. Remove from the heat, cool completely, discard the bay leaf and then stir in the cheeses and the oregano.

Preheat the oven to 420°F/220°C. Have ready two large baking sheets.
Divide the dough into 8 equal parts – each will be around 100g (3 ½ oz.). Roll out each portion of dough on a lightly floured surface until you get a rough 25cm (10in) circle. Place about ½ cup of the filling on one side of the dough and fold the other half over, pinching the seams well to keep the filling inside – since vegetables can vary in size, if you have a scale weigh the filling and divide it equally in 8 portions. Repeat the process with the remaining dough and filling. Place the calzones onto the sheets and brush them with the olive oil and sprinkle with the parmesan. Bake for about 20 minutes or until golden. Serve immediately.

* the yellow mozzarella I used is not like fresh mozzarella balls, therefore it does not release too much liquid. Replace by cheddar or something similar texture wise.
