Making the meatballs:
Line a cutting board with parchment paper.
Add all the “meatballs” ingredients to a food processor. Blend until smooth.
Transfer to a bowl, cover, and let sit for about 10 minutes.
Use a Tbs to measure 1 meatball.
Scoop a Tbs of the bean mixture and roll one meatball with your hands.
Transfer to a prepared cutting board. Repeat with the rest of the bean mixture. Set aside.
For the sauce:
Heat some oil in a skillet on medium heat. Add the onion and garlic and saute for about 2 minutes.
Add the crushed tomatoes, tomato paste, coconut sugar, white wine, basil, oregano, and mustard powder.
Let it simmer for about 4 minutes. Set aside.
Add the tomato mixture to a food processor together with the roasted peppers, salt, and pepper.
Blend until the mixture is smooth.
Heat another skillet with olive oil on medium heat. Add the meatballs and cook, stirring for about 2 minutes.
Add the blended sauce to the meatballs, turn the heat to low, cover and let it cook for about 7 to 10 minutes.
Undercook the spaghetti by 1-2 minutes.
Roll them into little beds and place one meatball on each one. You can grate some nut cheese on top.
Bake at 200 degrees C for 5-7 minutes.
