Gather the ingredients.
Combine all salad dressing ingredients in a cup and set aside. Place pineapple chunks in a mixing bowl.
To prepare cucumber: Remove skin with a vegetable peeler, then cut the cucumber in half lengthwise. Slice these sections again lengthwise (several times if the cucumber is thick), then slice the other way to create cubes or chunks. Add these to the mixing bowl.
Slice red pepper thinly to create matchstick-like pieces. Add these to the mixing bowl.
Add sliced spring/green onion, plus the whole roasted peanuts.
Add most of the basil and coriander, putting aside a little of each for the garnish.
Pour over the salad dressing over and toss well.
Scoop salad onto a serving plate and top with the extra basil and coriander, plus a good sprinkling of nuts.
If desired, serve with lime wedges on the side.
