Drain tofu in a colander, then weigh down tofu with something heavy. Let it sit in the sink while preparing the sauce.

Combine brown sugar, cornstarch, vinegar, soy sauce and juice from the pineapple in a saucepan. Bring to a boil until thick and clear.

Slice onion and pepper into thin strips. Combine with tofu and sauce and pineapple chunks. Heat until vegetables soften, then serve over rice or Chinese noodles.
