Add the lemon juice, ¼ teaspoon sea salt, pepper, garlic, and oregano to a small bowl. Stir to dissolve the salt.
Slowly add olive oil to the lemon juice mixture while continuously whisking until a smooth, pale yellow dressing forms. Place aside, now soften the cabbage.
Add the diced cabbage and 1 teaspoon sea salt to a large bowl.
Toss the cabbage with the salt and gently squeeze and massage to puncture and soften the leaves.
Place aside for 5 minutes.
When ready, rinse the cabbage with cold water, drain, and dry the cabbage ( I like to dry the cabbage with a salad spinner).
Add the cabbage and Greek dressing in a big bowl. Mix with two large spoons. Now let's put everything together.
Add the chives, bell pepper, cucumber, and mint to the cabbage. Toss once again to combine.
Serve immediately.
