Frequently Asked Questions About Sweet and Sour Meatballs
You can use any vegetables. you choose. If you don’t like peppers you can use sliced carrots for a healthy addition that brings a little crunch. Replace the slice onions with pearl onions for a change. Choose celery, green beans, jicama, broccoli, cauliflower, or any vegetables that you enjoy.

Repeat each layer once, or simply finish off with one more meatball. Add extra sauce on the side, or drizzle the kabobs with a little extra once they’re on the serving dish.
- Bread: Instead of bread soaked in milk, you can use breadcrumbs in this homemade meatball recipe. Add ½ cup dry bread crumbs, either regular or panko, and reduce the milk to ¼ cup. You just want enough milk to make the crumbs moist but not dissolve them.
- Juice: For a tangier citrus sauce, use orange juice instead of pineapple juice. You could also try tropical juice blends or use half pineapple juice and half other juices. Try not to use juices that are overly sweet with added sugar, or reduce the brown sugar to taste.
- Sauce Ingredients: You can add other popular Asian flavorings like chili garlic sauce, oyster sauce, rice vinegar, green onion, sriracha, or other seasonings to your taste.
