Take a decent sized cling film, put the onion with the cut part down in the centre. Close the cling film over the round part and twist all the air out of the wrap.
The onion will stay good in the fridge for some days.
- Cucumber << water, water, water +++
- Tomatoes << water, water
- Onion << water
Do you see how much water each of those main ingredients contain?
Let's take one at a time.
Onions:-
Fresh onions are not only have a high volume of water, also natrual chemicals that make strong pungent flavour. These chemicals (e.g. Sulphur) work quite well with oxygen in the air, resulting the bitterness.
In order to tone down
the flavour and bitterness, soack the onions in ice water.
Another method is to add fresh lime juice immediately after slicing/dicing the onions.
Cucumber:-
Cut and remove the entire section of seeds. Now dice the cucumber.
Remember the little science projects about drawing out excess water from vegetables?
Soak Cucumber in ice water with little salt. (Perhaps you could refrain from adding salt to the final salad bowl, if the quantity used at this point suffice)
Same theory goes for making potato chips. Slice potatoes are soaked in water to draw out that extra moisture. No ricket science here though ;)
Tomatoes:-
Remove entire section of seeds. Dice them and add into your salad.
Garam masala has Fennel and Cineman, that has the sweetness. It's also possible restaurant adds in a bit of sugar. However, certain onion species are sweeter naturally.
To be frank, we don't use garam masala, mint or corriander. Insated you could have the following simple ingridients to make a heaven of a salad, if you may.
fresh :{cucumber, tomatoes, onion, spicy green chilli, black pepper, salt, lime}
Bon appetit!

Some slime building is normal in onions and related vegetables, see this question. It is less pronounced in bulbs than in leaves, but it can occur. If your onion bulb is solid, there is no problem with it.
Sometimes you can have spoiled slimy onion bulbs. In this case, spoilage microorganisms eat away the firm cell structure of the onion and leave you with slimy mush. You can recognize this easily: if it has happened, the onion has a patch which feels really soft, and is much slimier than the rest. It is often discolored, and can also smell strange. It looks and feels very different from a healthy onion with a slight slime layer. I can't be 100% sure as I haven't seen your onion, but from your description, it sounds like it wasn't the case this time.
