I wanted to cook something quickly. I had chicken. Spaghetti are fast. And I had fresh tomatoes from the garden of good friends. There are always onions and various spices around.
Simple.
But now about that madness aspect of it...

Take some garam masala and curry powder (or ingredients thereof of your choice), fry it in a little olive oil, add some chopped onion and black pepper, until the spices' smell reaches its peak. Then add the chicken (pieces of breast meat in that case) to brown it and get it happily accustomed to its flavoring friends. When the chicken is nice and brown, add some tomatoes, and to give it a little edge, some apple cider vinegar. Just a dash will do to bring out the tomato acidity a little better and contrast what is coming next: add the raisins.
Oh, I forgot that chili pepper I threw in with the spices for good measure.. but you probably thought of that yourself..

Oh, and what my friend means with "crazy" is "crazy good"..
