1 tablespoon tomato paste dissolved in 3 tablespoons water
1 teaspoon fresh lemon juice
Salt and freshly ground pepper
6 semi-ripe medium unpeeled bananas
1 small red bell pepper, minced
Preheat the oven to 400°. Heat the oil in a nonreactive skillet. Add the beef and brown over high heat, breaking it up with a wooden spoon, until cooked through. Add the onion, garlic and curry powder and cook, stirring until fragrant, about 4 minutes. Stir in the tomato paste and lemon juice and season with salt and pepper.
Using a small knife, cut each banana lengthwise just through the top skin. Pull the skin apart slightly and stuff each banana with the curried beef. Arrange the bananas in a roasting pan, cover with foil and bake for about 25 minutes, or until the bananas are tender and heated through. Sprinkle with the red pepper and serve.
