Tomato, Chicken and Basil Pasta

It can sometimes be extremely difficult to cook anything impressive or avant grande when you're stuck in a kitchen with basic foods, as I experienced yesterday thanks to the snow.
Therefore, I resorted to making something simple given the circumstances. The Pasta took me an hour to make and was far better than the frozen pizza that I had contemplated eating before.

INGREDIENTS:
*3 whole plum tomatoes-roughly chopped.
*2 tins -400g of chopped tomatoes
*squeeze of tomato purée
*2 TBSP of natural yoghurt
*2 cloves of finely chopped garlic
*1 whole onion-finely sliced.
*1 TBSP of dried Rosemary
*2 TBSP of oregano
*1 TBSP of paprika
*1 TBSP of crushed pepper and 1 TBSP of salt
*Handful of finely chopped basil.
 *4 precooked breast fillets, chopped into chunks
*1 TSP of crushed birds eye chillies
*500g of pasta of your choice.
*Sunflower oil
*2-3 TBSP of plain flour
* A Finely chopped Zucchini
METHOD: 
1.) Begin by pouring the tinned tomatoes into a bowl, along with the purée and chopped fresh tomatoes. Then add the yoghurt too, and mix the ingredients together, so that the yoghurt blends in. 
2.) Next place the sunflower oil into a frying pan, when its heated add the chopped onions and half the garlic in. Allow 3-4 minutes for the onions to transform into a golden colour.
3.) Then add the tomato mixture into the hot frying pan and stir for a while, before placing a lid onto the pan.
Leave on a high heat for up to 5 minutes, before lifting up the lid and adding the flour to the bubbling mixture. Take care to fold the flour in gently, it should thicken the sauce (if it doesn't try adding more flour, in small quantities though)
4.) Now place a saucepan with kettle-hot water on the hob and pour in the pasta. This should take up to 15 minutes to cook until soft. 
4.) Next, add the cooked and chopped meat in, as well as the Zucchini to the tomato sauce.
As well as adding the: rosemary, paprika, oregano, chillies and basil.
Stir the mixture well, adding salt and pepper to enhance the taste.
The cover the sauce and leave on a low heat, and wait until  the pasta has been cooked.
6.) Once the pasta is soft, take it out of the water and place back into the draw saucepan. Pour a generous helping of olive oil on top of it and add the remainder of the garlic. Mix well and then place the garlic-y pasta into the pan with the sauce mixture.
Spend a few minutes, folding the pasta into the sauce, and then heat it for a few more minutes, before serving.

When serving, garnish the pasta with olive oil, pepper and parmesan for the best result.
