I remember hearing a sentence with the word "one".
There are three tomatoes. Two of them are red. The ones being red are so delicious.
Is the usage of "the ones" correct? I don't even know if there is a usage like that. And I've also tried to reduce the clause "that are red" into "being red" but I'm not sure if it's true or not. I'd be grateful if you could answer both of these questions.
