Grilled Meatballs with Easy Tzatziki

Grilled Meatballs with Easy Tzatziki 

Recipe from: 
Serves 6 - possibly 8

For the meatballs:
2 lbs lean ground beef (I recommend grass-fed beef)
1 small-ish Vidalia onion or brown onion 
1 zucchini
1 garlic clove 
1/2 teaspoon garlic powder
1 teaspoon kosher salt
1/2 teaspoon fresh ground pepper
1 teaspoon dry thyme
1 tablespoon minced fresh basil (optional, I have made it without this and they are still delicious)
olive oil for brushing and grilling
sea salt for finishing 

For the tzatziki: 
*recipe can be doubled*

1 cup Greek yogurt (any percentage of fat is fine)
1 clove garlic
1/2 teaspoon lemon zest
1 tablespoon lemon juice
1/2 cucumber sliced
1 tablespoon olive oil
salt and pepper to taste.

Line a baking sheet with tin foil. Brush a thin layer of olive oil on the tin foil.

Shred your zucchini using a hand grater or the shredding attachment on your food processor. Place shredded zucchini in a paper towel to absorb excess moisture. Set aside.

Clean out food processor if using. Cut up your onion into chunks and place it in food processor with garlic. Process into a purée. Place mixture in a fine mesh sieve set over the sink or a bowl to allow excess water to drain away. You can also grate the onion and garlic with a hand grater if you would like. 

Place zucchini, drained onion, garlic powder, salt, pepper, thyme, and basil in a bowl. Mix well. I use my hands. Add ground beef and mix again, using hands to incorporate the ingredients evenly. 

Using a medium sized ice cream scoop - mine is stated at being 5 cm and producing meatballs about the size of golf balls - scoop out even sized balls and place on oiled cookie sheet. Press each meatball just slightly down to make it a little flatter. 

Once you have all your meatballs scooped, brush each with olive oil and sprinkle with sea salt.

Prepare your grill on medium heat. 

Make your tzatziki. In a clean food processor or blender combine, yogurt, minced clove of garlic, sliced cucumbers, lemon zest, lemon juice, salt, pepper, and olive oil. Blend until everything is well mixed and cucumber is minced. Some larger slices or chunks are ok too! Place in a bowl and set in the fridge to chill and relax and let all the flavors blend. 

Once your grill is hot, brush grill grates with olive oil. Grill meatballs. About 5-7 minutes per side, or until meat is cooked through or to your liking. Serve with tzatziki.
