A bright, make-ahead side
Guineos en escabeche pairs cooked green bananas with a vinegar-and-oil dressing, onion, peppers and seasonings. The bananas are tender but firm, so they hold their shape while taking on the dressing’s tang. Served chilled, the salad makes a refreshing counterpoint to rich roasted foods, grilled vegetables or seafood. It is a practical dish for entertaining because you can prepare it before guests arrive.
Choose firm, fully green bananas rather than ripe yellow ones. Green bananas are starchy and mild; ripe bananas become sweet and soft when cooked and will give the salad a different texture. For about six side-dish servings, gather eight small green bananas, one medium onion, one red bell pepper, one green bell pepper, three garlic cloves, ½ cup olive oil, ⅓ cup white vinegar, two bay leaves, ½ teaspoon dried oregano, salt and black pepper. A small handful of sliced olives is optional.
Peel and cook the green bananas
Green banana peels cling tightly to the flesh and can leave a sticky residue on your hands. Trim both ends of each banana, score the peel lengthwise without cutting deeply into the flesh, then work a thumb or the edge of a spoon under the peel. Lightly oiling your hands can make the job less messy. Cut the peeled bananas into thick rounds and place them in a bowl of cool water while you finish the batch to limit discoloration.
Bring a pot of water to a boil, add a generous pinch of salt, and cook the banana rounds until a fork slides in with slight resistance, usually about 15 to 25 minutes depending on their size. Check a piece early: the goal is tender, not falling apart. Drain well and let the rounds cool while you prepare the dressing. If a few pieces break, they will still taste good, but gentle handling helps the finished salad look its best.
Build the escabeche dressing
Thinly slice the onion and peppers, and mince the garlic. Warm the olive oil in a wide pan over medium-low heat. Add the onion, peppers and bay leaves, then cook gently until the vegetables soften but retain some bite, about 8 to 10 minutes. Stir in the garlic and oregano for the final minute. Avoid browning the garlic, which can give the dressing a bitter edge.
Take the pan off the heat before stirring in the vinegar. Season with salt and black pepper, then taste a spoonful of the dressing once it has cooled slightly. It should be distinctly tangy but not harsh; add a little more oil if the vinegar dominates, or a splash more vinegar if it tastes flat. Fold in the olives, if using. Different vinegars vary in sharpness, so tasting is more reliable than treating the proportions as fixed.
Combine, chill and serve
Put the drained bananas in a large bowl and pour the warm dressing and vegetables over them. Fold gently until the pieces are coated, taking care not to mash them. Let the salad cool briefly, then cover and refrigerate. A few hours of chilling gives the flavors time to mingle; stir gently before serving so the dressing reaches the pieces at the bottom of the bowl. Remove the bay leaves, taste for salt and offer extra vinegar at the table for anyone who prefers a sharper bite.
For a little variation, add a few sliced pimientos for color or finish the salad with chopped parsley. Keep additions modest so the green bananas and escabeche dressing remain the focus. Serve the salad cold or let individual portions lose their refrigerator chill for a few minutes; do not leave the full bowl sitting out through a long meal.
Handle and store it with care
Wash the peppers and other fresh produce, and use clean utensils and a clean serving bowl. Refrigerate the finished salad promptly in a covered container, ideally within two hours of preparation, and keep it at 40°F (4°C) or below. Use leftovers within three to four days. Vinegar adds flavor, but it does not make the salad shelf-stable; do not store it at room temperature.
If you serve guineos en escabeche alongside seafood, keep raw seafood and its juices away from the salad and from utensils used to serve it. Citrus or vinegar can change the appearance and texture of raw seafood, but citrus curing does not make it equivalent to cooked seafood. A chilled side dish is best kept separate from raw-seafood preparation.
