Heat a 1/2 inch of vegetable oil in a large saucepan over medium-high heat. Fry eggplants in batches until golden brown, about 1 minute per side. Transfer to paper towels to drain.
Puree tomatoes in a blender until smooth. Press through a strainer, discarding seeds and skins.
Heat olive oil in a large skillet over medium heat. Add onion and garlic; cook and stir until translucent, 3 to 5 minutes. Add beef and cook until no longer pink, about 5 minutes. Stir in potato, green bell pepper, and tomato paste. Season with salt and pepper.
Stir tomato puree into the skillet. Simmer until sauce thickens, about 10 minutes. Add fried eggplant and lemon juice. Simmer until flavors combine, about 5 minutes more.
For a healthier version, roast eggplants instead of frying them.
We have determined the nutritional value of oil for frying based on a retention value of 10% after cooking. Amount will vary depending on cooking time and temperature, ingredient density, and specific type of oil used.
