If you like spicier dishes, you can't go wrong with ma po tofu. it's dead easy.
500 g regular firm tofu, not the silken stuff which should be used in soups
250 g ground pork
2 tbsp hot bean paste (Lee Kum Kee and others make this). perhaps try 1 tbsp first then check for taste
2 tbps soy sauce
2 cloves garlic, minced
one thumb minced ginger
4 tbsp chopped green onion
1/2 to 1 cup or so of chicken broth
oil for frying pork
stir fry pork, dump in liquids. drain tofu, cut into small cubes and pour them in, stir gently to heat through, check sauce. add salt, pepper or more bean paste to taste. some peopel add a dash of sesame oil
serve with steamed rice and perhaps a steamed veggie. you can stretch this with those dry soy crumb things that health food stores sell and make a total veggie version.
