Hmm...don't really have a signature dish.
Although this week i made paella which turned out to be very nice, spicy butternut squash soup and cherry cake. I also did chicken fajitas with bombay potatos but i overcooked the potatoes and it turned into spicy mash!
Paella was really simple though....but you really need a large pan for it (i used my mates wok).
Heat some oil in a pan and add 1 chopped onion and 1 red pepper (sliced). Cook for 5 mins then add chopped garlic (2 cloves), 230g tinned chopped tomatoes, and 1tsp of tumeric and cook for 1 more min (i added more tumeric). Add 300g rice and cook for 1 min before adding 1,3 litres of veg stock. Stir and bring to the boil. Its a case of waiting for the rice to cook now so keep trying it and add more water if need be. Once done, add 400g seafood and 175g of halved green beans and cook for 5 mins.
All depends on what you have in the kitchen really- for example the soup requires a blender (but is dead easy as well)
