To make the sauce: Heat a pot over medium heat and add the olive oil, followed by the garlic cloves. Cook until just beginning to brown, then immediately add the crushed tomatoes along with the salt. Turn the heat to medium-low and continue to cook until the sauce thickens into your preferred marinara consistency, mine is around 20 minutes for a slightly thick sauce. Stir in the sugar and harissa. Taste and if the flavor is to you’re liking, remove from heat.
To make the meatballs: Preheat your oven to 400˚F. Drain but do not press the tofu. Using your hands, crumble the tofu into a medium bowl until there are no pieces of tofu larger than pea-size. Add the eggs and stir until eggs are mixed in with the tofu. Measure in the panko along with the minced garlic, doenjang, nutritional yeast, and salt. Stir until well combined, using the back of the spoon to mash any larger pieces of tofu as you go along.
Grab a sheet tray and drizzle with about 2 tablespoons of olive oil and place in the preheated oven while you shape the meatballs.
Scoop out roughly a ping pong-size of the mixture and roll into a ball. Place on a plate and repeat with the remaining tofu mixture. Once you have formed all the meatballs, remove the preheated tray from the oven. Place the meatballs on the tray, then brush the meatballs with some of the olive oil.
Bake the meatballs for 15 minutes then remove from the oven, brush the tops with residual oil and return to the oven. Bake for another 10 minutes or so, until the meatballs are browning and have a crispy exterior.
To serve: divide the meatballs into four bowls with the garlic bread and top with sauce.
