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.
You can absolutely fry tomatoes, half, sliced, or whole, without fat. And tomatoes have enough water not to stick or burn. (You may want to watch and adjust the temperature)
You may argue that’s booling or steaming, not grilling, but the outcome will be fine.
