Prepare Tofu: Cut tofu into 1-inch cubes and press to remove excess moisture.
Coat Tofu: Toss the tofu cubes in a mixture of cornstarch, salt, and pepper until evenly coated.
Preheat Air Fryer: Set air fryer to 400°F (200°C) and allow it to preheat.
Cook Tofu: Place the tofu in a single layer in the air fryer basket, cooking for 15 minutes, shaking halfway through for even crispiness.
Chop Vegetables: While the tofu cooks, chop the bell peppers and onion.
Sauté Vegetables: In a skillet, sauté the vegetables over medium heat until tender-crisp.
Combine Ingredients: After the tofu is cooked, add it to the skillet with the sautéed vegetables. Pour in the sweet and sour sauce and toss to coat.
Serve: Garnish with sliced green onions or sesame seeds. Enjoy with steamed rice or noodles.
Achieving Crispy Tofu: Ensure proper moisture removal and even cornstarch coating for best crispiness.
Fresh vs. Canned Pineapple: Fresh pineapple adds a vibrant flavor, while canned pineapple provides convenience.
Vegetable Variations: Experiment with broccoli, snap peas, or carrots for added nutrition and flavor.
