Preheat Oven and Prepare Muffin Tin: Preheat your oven to 180°C (350°F). Grease a muffin tin with olive oil or line with muffin papers.

Mix Wet Ingredients: In a large bowl, whisk together the eggs, melted butter, and milk until well combined.

Combine Dry Ingredients: In another bowl, mix the flour, semolina, baking powder, salt, and black pepper.

Prepare the Filling: To the wet ingredients, add the grated zucchini, grated potato, chopped onion, diced tomato, chopped bacon, and grated cheese. Mix well.

Add Flour Mixture: Gradually fold the dry ingredients into the wet mix, ensuring not to overmix.

Prepare the Muffin Batter: Combine all ingredients thoroughly until you have a homogeneous batter.

Spoon into Muffin Tin: Spoon the batter into the prepared muffin tin, filling each cup about three-quarters full.

Bake: Bake in the preheated oven for 20-25 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.

Prepare the Sauce: While the muffins are baking, mix together sour cream, mayonnaise, French mustard, dried garlic, and chopped parsley to create a creamy sauce.

Serve: Allow the muffins to cool slightly before removing them from the tin. Serve warm with the prepared sauce.
