First of all cook your cous cous. The ratio here is 1:1 so for ½ up of couscous we'll use ½ cup of boiling water.
Bring ½ cup of water and add couscous to the water.
Do not disturb the couscous, let it fully absorb the hot liquid. Stir your couscous in the boiling liquid and remove from heat immediately. Quickly cover the saucepan with a lid and let the couscous sit for about 10 minutes undisturbed until it has fully absorbed the liquid.
Meanwhile chop cucumber and beetroot in very small cubes.
Finely chop herbs and garlic.
When the couscous is cooked transfer it to the bowl, add vegetables and herbs.
Toss everythin in salt, olive oil and lemon juice.
Serve it hot or cold, enjoy!
