I make my own pizza and spaghetti sauce which is authentic Italian. I start by slicing fresh garlic very, very thin and saute' them in olive oil. Using that as a base, I build the sauce from there. I let the sauce simmer all day on relatively low heat. I make a lot of it and freeze everything in serving size containers.
I have fried sliced fresh potato's and fried them but generally, this is unhealthy. You might want to consider a oil-less air fryer. It uses little to no oil and can fry food like chicken, fries or fish as well as a grease fryer. They come in different sizes and configurations and a number of them have adjustable heat ranges for a slower cook. This method generally gives you a more thorough cooking job and consistency. The best part is you can indulge in your favorite fried food recipes without the calories and artery clogging fats.
You can cook other things in the oil-less fryer including steak. It generally cook everything pretty fast depending on the settings. Give it a try and see if this doesn't make you a kitchen, culinary hero.
Here is a link to the oil-less fryer.
