Make the dressing
In a bowl, mix the plant-based Greek-style yogurt, minced garlic, chopped dill, lemon juice, olive oil, salt, and black pepper. Stir until smooth. Taste and tweak the salt or lemon — balance matters.
Slice the cucumbers & onions
Thinly slice the cucumbers (use a mandoline or a steady hand). Add the sliced cucumbers and red onion to a large bowl.
Toss and finish
Pour the dressing over the cucumbers and onions. Toss until the salad coats evenly. Taste and adjust salt or lemon if needed.
Serve immediately
Serve right away for the crispest texture. You can chill it for 10–15 minutes if you prefer it extra cold.
Bold serving suggestion: garnish with extra dill or a sprinkle of lemon zest for a bright finish.
