+Given the command:
+Create a full Vietnamese banh mi recipe from the following ingredients: pork belly, carrot, pate, eggs. Based on the ingredients and instructions of the generated recipe, do the following tasks:
+- describe the image of the final dish
+- estimate the calories (give number, no explanation)
+- Estimate healthiness score in scale 0 to 10 (give number, no explanation)
+- Estimate average percentage of vegetables, whole grains, healthy protein, fruits, and healthy oils in the final dish (give number, no explanation).
+The corresponding answer is:
+Ingredients:
+•	1 baguette
+•	1/2 lb pork belly, sliced
+•	1 cup grated carrots
+•	1/2 cup pate
+•	2 eggs
+•	2 tbsp soy sauce
+•	2 tbsp fish sauce
+•	2 tbsp sugar
+•	2 tbsp vinegar
+•	1/4 cup mayonnaise
+•	1/4 cup sliced jalapeños
+•	Cilantro leaves, for garnish
+Instructions:
+1.	In a bowl, mix together the soy sauce, fish sauce, sugar, and vinegar. Add the sliced pork belly and let marinate for at least 30 minutes.
+2.	Heat a pan over medium-high heat and cook the marinated pork belly until golden brown and crispy, about 5-7 minutes on each side.
+3.	In another pan, scramble the eggs until fully cooked.
+4.	Cut the baguette in half and spread mayonnaise on both sides. Layer on the cooked pork belly, scrambled eggs, grated carrots, sliced jalapeños, and cilantro leaves.
+5.	Spread pate on top of the other half of the baguette and place on top of the sandwich.
+6.	Serve immediately.
+Image of final dish: The Vietnamese Banh Mi is a sandwich that is typically served on a crispy and crusty baguette. The sandwich is filled with layers of sliced pork belly, scrambled eggs, grated carrots, sliced jalapeños, and cilantro leaves. The pate is spread on the top of the sandwich, giving it a rich and savoury flavour.
+Estimated calories: Approximately 650-700 calories per sandwich.
+Healthiness score: 5 out of 10. While the sandwich contains some vegetables, protein, and healthy oils, it is also high in calories and fat due to the pork belly and pate.
+Estimated percentage of food categories:
+Vegetables: 20%
+Whole grains: 20%
+Healthy protein: 30%
+Fruits: 0%
+Healthy oils: 5% (mayonnaise)
+The standardized form of the above answer is:
+Ingredients: ['1 baguette', '1/2 lb pork belly, sliced', '1 cup grated carrots', '1/2 cup pate', '2 eggs', '2 tbsp soy sauce', '2 tbsp fish sauce', '2 tbsp sugar', '2 tbsp vinegar', '1/4 cup mayonnaise', '1/4 cup sliced jalapeños', 'Cilantro leaves, for garnish']
+Instructions: ['In a bowl, mix together the soy sauce, fish sauce, sugar, and vinegar.
