- Combine cucumber, tomatoes, jalapeño peppers, onion and cilantro in medium bowl. Whisk sugar, rosemary, thyme, pepper, lemon and lime juices, vinegar and olive oil in a small bowl; pour over vegetables. Sir to combine. Chill 1 hour for best flavor.
- Heat approximately 2 inches of oil in a deep saucepan. Cut plantains into thirds, crosswise. Slice each third lengthwise into very thin 1/4-inch slices. Deep fry a few slices at a time until golden, about 2 to 3 minutes; remove with a slotted spoon. Place chips on absorbent toweling and sprinkle with garlic salt.
A mandolin slicer works well to make uniform, thinly sliced chips.
