Sweet and Sour Tofu!

Recipe from here, but I didn't use the pineapples or bell peppers. Just peas and green onions. Plus I used olive oil:

Ingredients
3 tablespoons rice-wine vinegar
2 tablespoons ketchup
2 tablespoons reduced-sodium soy sauce
1 tablespoon brown sugar
1 14-ounce package extra-firm water-packed tofu, drained, rinsed and cut into 1/2-inch cubes
2 teaspoons cornstarch
2 tablespoons olive oil, divided
2 tablespoons minced garlic
1 tablespoon minced ginger
As preferred: green peas or onions or any other veggies you like!

Prep
1. Drain and set aside pineapple, reserving 1/4 cup of the juice. Whisk the reserved pineapple juice, vinegar, ketchup, soy sauce and sugar in a medium bowl until smooth. Place tofu in a large bowl; toss with 3 tablespoons of the sauce. Let marinate for at least 5 minutes and up to 30 minutes.

2. Meanwhile, add cornstarch to the remaining sauce and whisk until smooth.

3. Heat 1 tablespoon oil in a large nonstick skillet over medium-high heat. Transfer the tofu to the pan using a slotted spoon; whisk any remaining marinade into the bowl of reserved sauce. Cook the tofu, stirring every 1 to 2 minutes, until golden brown, 7 to 9 minutes total. Transfer to a plate.

4. Add the remaining oil to the pan and heat over medium heat. Add garlic and ginger and cook, stirring constantly, until fragrant, about 30 seconds. Add red and green peppers and cook, stirring often, until just tender, 2 to 3 minutes. Pour in the reserved sauce and cook, stirring, until thickened, about 30 seconds. Add the tofu and pineapple and cook, stirring gently, until heated through, about 2 minutes more.
