Preheat the oven to 425°F. Line a baking sheet with parchment paper.
Roughly chop the parsley and add it to a big bowl. Add the ground beef, parsley, garlic paste, salt, pepper, milk, breadcrumbs, and eggs to the bowl and combine.
Use two spoonfuls of the mixture to make each meatball. Or 1 scoop of a medium cookie scoop. Shape into 1 ½-inch balls and place them on the baking sheet.
Bake for 24 minutes and turn halfway through, so the bottoms don't brown.
Sauce
Place the guava paste in a deep bowl and heat it up in the microwave for 30 seconds. Mash the pasta and combine it with the water.
In a big pan, add the bbq sauce, guava sauce, and meatballs. Cook for 6 minutes over medium heat while stirring. Serve and enjoy!
Notes
I have made this recipe with and without the Parmesan cheese. They both turn out great, but with the cheese, it adds a layer of flavor.
If you don't want to make the meatballs, you can use frozen ones.
To store the meatballs, cool them down first. Then store them in a freezer bag or an airtight container for up to 4 days in the fridge and 3 months in the freezer.
