"Also, some of my own, when I was alone are not measured. Wouldn't work with say bread making but take some mince, some onion some carrot, etc. and put in a pan can work. Just use qtys that look right."

Yeah, there's a lot of unecessary mysticism around cooking (I blame all of these TV chefs). Get yourself a good stout pan with a lid. Start by adding a couple of teaspoons of cooking oil (ordinary supermaket own brand vegetable oil will do). Chop up an onion, heat the oil in the pan, chuck in the chopped onion and stir it round until it just begins to brown. Chuck in some meat and brown that together with a few chopped vegetables (mushrooms, peppers, carrots - whatever)and chopped garlic . Stir a bit more (try not to burn anything). Hurl in a can of chopped tomatoes and the same volume of water (use the tomato can as a measure). Add a pinch of salt and a few dried herbs. Put the lid on the pan and simmer on low light for no more than an hour. Serve with rice or pasta. Easy! Even I can do it.

You may need to experiment with a few of the variables - but it's usually edible first try.
