Peel and finely slice garlic. Finely slice zucchini into coins as thin as you have the patience for. Heat a few tablespoons olive oil in a large saucepan.
Cook zucchini and garlic over a medium high heat for a few minutes, or until the zucchini is starting to soften.
Add tomatoes, beans and the juice from both the cans. Simmer for another 5 minutes or until the zucchini is cooked through.
