In a bowl, whisk together mayonnaise and yellow mustard until well combined.

Gradually whisk in olive oil, ensuring the mixture retains a mayonnaise-like consistency.

Add hot sauce (Tabasco or Louisiana hot sauce) and whisk to combine.

Incorporate ketchup by whisking it into the mixture.

Add the seasonings (garlic salt, salt) and wine vinegar, whisking to ensure they are evenly distributed.

Gradually add lemon juice while beating thoroughly to prevent curdling.

In a large bowl, combine shredded cabbage, sliced bell peppers, and minced onions.

Pour the prepared dressing over the vegetables.

Stir well to coat all the vegetables evenly with the dressing.

Refrigerate for at least one hour, or preferably overnight, to allow the flavors to meld before serving.
