Prepare the Produce: Wash the cucumber and slice it thinly. Dice the avocados and slice the red onion very thin for a milder flavor.
Mix the Dressing: In a small bowl, whisk together lime juice, olive oil, minced garlic, honey, cumin, salt, and pepper. Taste and adjust seasoning — it should be tangy and refreshing.
Combine the Ingredients: Place cucumber, avocado, onion, and cilantro in a large mixing bowl.
Add the Dressing: Drizzle the lime dressing over the salad. Toss gently with a spoon or rubber spatula to mix evenly, being careful not to crush the avocado.
Final Touches: Sprinkle with a little more salt, pepper, and fresh cilantro before serving. Optionally, top with chili flakes for heat.
