My dad used to make something similar to that second link when we were kids. A slice of bread, some mayo, tomato slices, salt and pepper, top with American cheese. Pop it in the oven on a cookie sheet until the bread is toasty and cheese is melted. It's quite good - but as you said, one has to have fresh tomatoes. A grocery store tomato will not cut it if you're making those!
