Preheat oven to 375 degrees F.
Combine eggplant, soy sauce and first amount of oil. Toss to coat.
Bake until fork-tender and soft, 10 to 13 minutes.
In sauté pan over medium-high heat, heat second amount of oil. Add onion and garlic. Sauté until translucent, 1 to 2 minutes.
In mixer bowl with paddle attachment, combine eggplant, Quinoa, onion garlic mixture, nutritional yeast, basil and oregano. Mix on low speed until well combined, 3 to 4 minutes. Do not overmix.
Combine eggplant mixture, flour (we use a gluten-free version) and salt. Fold until well blended.
On parchment-lined sheet pan(s), portion 12 eggplant meatballs 1" apart. TIP: Use a #30 scoop (or medium sized scoop).
Bake, stirring once, until golden brown, 25 to 30 minutes.
Serve with your favorite marinara sauce.
