1) Heat a large skillet over medium heat. Add the oil and garlic, and saute until the garlic is golden, about 2 to 3 minutes. Remove and discard the garlic.
2) Increase the heat to high and add the squash. Saute, tossing frequently until crisp-tender, about 5 minutes. Add the tomatoes and mint and cook until warmed, about 1 minute more. Season with salt and pepper to taste.
