This is one of the simplest recipes for using courgettes, getting some of the glut used up. It makes a tasty side-dish to accompany whatever you may be eating.
Simply slice the courgettes into piece about 1/2cm thick and put in the oven/under the grill for 10-15 minutes to cook gently/soften.
When soft(ish) cover with finely grated parmesan and put back under the grill until the cheese is cooked & golden brown.
Serve hot.
Depending on how mature the courgettes are, they could have more or less juice which will be hot so be careful.
