In a very large sauté pan cook you ground chicken until crisp. Mash while cooking well with a wooden spoon so the pieces are small. Remove from the pan. Add some vegetable oil, maybe a tablespoon or so depending on how much vegetable you are using. Add veggies to the pan and sauté over medium heat until the vegetables are tender. Add the garlic and the ginger and continue to cook another minute or so.

Meanwhile boil a pot of water, when water boils, remove from heat and add the udon. Let the noodles sit for one minute - that's it, if you leave them longer they will get gummy. Stir gently to break up noodles, then drain in a colander and drizzle with a little bit of sesame oil (use olive oil if you don't have sesame).

Add the ground chicken back to the vegetables and mix together. Add the noodles, soy, mirin, rice vinegar and sambal, and toss together until everything is mixed together and the noodles meat and veggies are draped in glorious sauce.
