Sweet and Sour Tofu

1 (20 ounce) container tofu
1 (20 ounce) can pineapple chunks or tidbits
1/4 cup packed brown sugar
2 tablespoons cornstarch
1/4 cup vinegar
1 tablespoon soy sauce
1 medium onion, sliced thin
Rice or Chinese noodles

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 tofu into cubes and add to sauce; marinate while rice cooks or 1 hour.

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.
