Here's a breakdown:
* wala means "no" or "without"
* lasa means "taste"
So, walang lasa literally translates to "without taste."
You can also use other terms depending on the context:
* maputla (pronounced "ma-put-la") - This means "pale" and can be used to describe something lacking in flavor or color.
* walang asim (pronounced "wah-lang a-sim") - This means "without sourness" and is specific to food lacking in acidity.
* walang alat (pronounced "wah-lang a-lat") - This means "without salt" and describes food lacking in saltiness.
The most appropriate term will depend on the specific context and the type of blandness you are trying to describe.
