Here is a recipe which I improvised today for a quick pasta sauce which I found particularly tasty:
Cold-pressed olive oil
Half a small onion, finely chopped.
Tiny amount of leftover juice from a ribsteak braised with onions
Half an Avocado, mashed
Chicken stock cube dissolved in hot water
Red chilli pepper deseeded and chopped
Saute the chopped onion in the olive oil and add the leftover ribsteak juice
Add a shake of Roma Passata and the mashed Avocado. Fold together.
Add the chopped chilli pepper
Pour in enough chicken stock liquid and stir to thin sauce to required consistency.
Add salt to taste.
Heat and serve over cooked tagliatelle, with or without grated parmesan.
Saute the chopped onions
