I like tomatoes and hot food but I don’t like to add much fat to my food, be it oil or butter. I won’t use lard.
Am I going to ruin the sliced tomatoes by grilling them on a pan just with salt and pepper?
I’m talking about 4 to 6 regular tomatoes per serving, half an inch thick slices.
As an aside, a thin coating of vegetable oil in the pan is going to be a pretty negligible day intake.
There are a lot of tools available to aerosolize or spritz oil too.
