If your rice noodles are not fresh, soften them by soaking them in hot (almost boiling) water for a few minutes.
Heat up some oil in a wok or skillet. Add bok choy (or other vegetable) and stir fry 2-3 minutes until cooked through. Remove from skillet.
Add tomatoes and garlic to skillet. Stir fry until tomatoes have gone soft and mushy and garlic is browned.
Divide your rice noodles into four bowls. On top of each bowl place 3-4 pieces fried tofu, bok choy, and about 1/4 cup cooked tomato garlic sauce.
Add water to each bowl, enough to create a soup for the noodles.
To each bowl add vinegar, soy sauce, and chili oil to taste. If you are unsure how much to add, start with 1 tsp vinegar, 1/2 tsp soy sauce, and 1/2 tsp chili oil. Mix your soup, taste, and continue to add seasoning as needed.
Serve each noodle bowl individually! Leftovers do not save, so eat fresh.
