In a hot skillet saute the cubed tofu until its brown. Set aside.
Saute onion then add bell pepper.
When onion and pepper are soft stir in remaining ingredients (except cooked tofu). Cook for 10-15 minutes. If your mixture becomes dry, try adding a bit of water.
Add your cooked tofu and serve.
Notes
If you happen to have some leftover, just store it in an airtight container and keep it in the fridge. We usually like to eat up leftovers within the next 48 hours, if at all possible. And once you're ready to eat it, you just need to get it out of the fridge and warm it up slowly in a skillet on the stove or zap it for a few seconds in the microwave.
