Creating Pineapple Tofu is a straightforward process. Follow these steps for a delicious result:

1. Prepare the Tofu: Start by pressing the tofu to remove excess moisture. Cut it into bite-sized cubes.
2. Marinate the Tofu: In a bowl, mix soy sauce, brown sugar, ginger, and garlic. Add the tofu and let it marinate for about 10 minutes.
3. Heat the Oil: In a large skillet, heat vegetable oil over medium heat.
4. Cook the Tofu: Add the marinated tofu to the skillet. Cook until golden and crispy, about 5-7 minutes, turning occasionally.
5. Add Pineapple: Stir in the pineapple chunks and cook for another 2-3 minutes until they are heated through.
6. Incorporate Bell Pepper: If using, add the sliced bell pepper and cook for an additional 3-4 minutes until tender-crisp.
7. Thicken Sauce: In a small bowl, mix 1 tablespoon of cornstarch with 2 tablespoons of water until smooth. Pour this into the skillet to thicken the sauce, stirring continuously for 1-2 minutes.
8. Finish Up: Add chopped green onions and mix well. Cook for a final minute.
9. Serve Hot: Remove from heat and serve immediately over cooked rice or quinoa.

Follow these steps, and you’ll be rewarded with a stunning and delicious Pineapple Tofu that will captivate your taste buds!
