Preheat the oven to 350 degrees Fahrenheit and line a shallow oven tray with baking paper. Add the ground almonds, ground flaxseed, coconut flour, baking soda, erythritol, and salt to a large mixing bowl. Mix together well to combine. You may use your preferred low carb sweetener if desired, adjusting quantities to taste.
Add the melted butter, apple cider vinegar, and yogurt to the bowl with the dry ingredients. Mix together well to combine. The mixture will be dry and crumbly.
Crack the eggs into the mixing bowl with the dry ingredients. Mix everything together well to combine. The mixture should start to hold together, forming a dough in the bowl.
Divide the dough into four even-sized portions and roll into balls. Arrange the balls of dough across the lined oven tray, pressing each one down slightly. Brush each ball of dough all over with a half tablespoon of olive oil.
Transfer the rolls to the oven. Bake for 20-22 minutes or until cooked through and golden brown all over. Set aside to cool and firm before serving.
