Combine in a glass bowl:
1 can French cut green beans, drained
1 can diced tomatoes, with juice (I prefer petite diced)
About ½ medium, white onion, diced
Several cloves raw garlic, minced
Cover and refrigerate to bring out the flavors. I let mine sit in the fridge for a few days this time, but you could serve it in just a few hours, or even right away in a pinch.
