Drain the tofu between paper towels until most of the water has been squeezed out.
Slice tofu into 1/4 inch thick slices.
Heat vegetable oil in a large skillet. Fry tofu strips until golden brown on both sides. Add onion and cook for a few minutes until onion is of desired doneness.
Pour in barbecue sauce (use more or less, according to your taste). Cook the mixture for 10 minutes on low and serve on buns.
