In a skillet over medium low heat, caramelize the onion until it's nice and brown. Add the garlic for just 30 seconds until it becomes fragrant.
While the onion is heating, mix together the tomato past, maple syrup, vinegar, soy sauce, mustard, salt, cayenne, water, and tamarind paste, whisking until smooth.
Put your beans in a casserole dish and add the sauce, onions, and garlic. Bake at 400° uncovered for about 30 minutes until sauce is bubbling and beans are cooked thoroughly.
