Thai Sweet and Sour Pork

2 tablespoons vegetable oil
1 (12 ounce) pork tenderloin, thinly sliced
1 small red onion, very thinly sliced
4 cloves garlic, crushed
1 red bell pepper, seeded and diced
3 large ripe plum tomatoes, quartered and thinly sliced

1 cup diced fresh pineapple
2 tablespoons fish sauce
1 tablespoon granulated sugar
2 whole scallions, finely sliced
Freshly ground black pepper to taste
Chopped fresh cilantro for garnish
Lime quarters for garnish
Minced hot chiles for garnish.

Heat oil in large nonstick pan over medium-high heat. Sauté onions until they soften and color. Add pork and brown quickly. Stir in garlic and sauté 30 seconds. Add red pepper and sauté until it begins to soften. Add tomatoes, cucumber and pineapple and cook a minute or two.

Lower heat and add fish sauce, sugar, scallions and black pepper. Stir well. If mixture seems too thick, add a little water. Sprinkle with cilantro. Serve with lime quarters and chiles.
