Spontaneous grilled cheese

Sandwich! Yum! My roommate and I spontaneously made these for lunch yesterday after returning from a bountiful trip to the grocery store. Both of us tend to shop at our local food co-op, but occasionally when we need to stock up, we hit Trader Joe's. Yesterday, even more unusual, we also went to the "real" grocery store, a magical big-box land of wide aisles and non-organic staples. We came home with plenty of recipes to make for the next several days but nothing planned for lunch, so we threw together this sandwich.

Gruyere cheese, red onion, bacon, apple, and thyme. Yum. We sauteed the onion, bacon, and thyme together, and added them to pan-grilled buttered bread along with grated gruyere. The apple was a last minute addition.
