My wife and I had grilled cheese sandwiches and tomato soup tonight for dinner.
This might not sound very exciting, but, I put a little extra in the sandwiches. This is something I've been doing for many years.
The little extra is onions & jalapenos. I slice the jalapenos and dice the onion and sauteed them together in butter until transparent.
Prepare grilled cheese as normal and add the onion & jalapeno, brown bread and enjoy.
