These are my favorite foods, wow it looks good! The veg looks fantastic, so does the meat, cast irons rock. I also don't have a grill, but the cast iron does a good job charing stuff.
Corn has been in season, so I've been shucking two of them into the pan with a touch of oil until they brown and cook. I use a lid and steam it a bit at the end. It takes a bit of time to get roasted right. Once done, I like to cut the corn off the cobb and add it to salads, this ones my favorite,
diced: 2 fresh jalapenos, 1 whole red bell pepper, 1 large cucumber, or two small, 1/2 white or red onion, cilantro, 2 ears of roasted corn + Oil, lime juice, salt, pepper and enough paprika you can see the color
