Take a large serving bowl in any shape that you like and set it on your kitchen table in order to mix the ingredients of Colorful Coleslaw.
Place 3 tablespoons of grainy mustard, 2 tablespoons of pure honey, 2 tablespoons of fresh lime juice, 2 tablespoons of cider vinegar, 2 tablespoons of extra-virgin olive oil, ½ tablespoon salt, and ¼ tablespoon of freshly ground black pepper in the bowl.
Note: Be very careful about the quantities of the ingredients while adding them in the serving bowel as a slight change in the proportion can bring a huge change in the taste of Colorful Coleslaw. However, you can make adjustments in the mentioned quantity of salt and black pepper according to your taste.
Coming back to the Colorful Coleslaw, grab a large whisk and mix all the ingredients in the bowl vigorously for a few minutes.
Continue mixing until you feel that the dry ingredients absorb the liquid ones properly.
Now, cover the bowl with a plastic wrapping sheet and place it in a refrigerator for 10 to 15 minutes or until marinated and chilled well.
Note: You can also set the bowl at room temperature to marinate but make sure that the room temperature is not too high.
In the meantime, wash the fresh vegetables including cilantro leaves, large head red cabbage, carrots, fennel bulb, and red onion.
Now, it is the time to cut the vegetables down. Take a sharp knife, place the fresh cilantro leaves on a cutting board and chop them finely.
Set the cilantro leaves on a side of the cutting board and cut the large head red cabbage into equal thin slices.
Slice the large carrots as well.
Thinly slice one medium fennel bulb and then thinly slice one red onion.
Remove the bowl from your refrigerator and top the mixture in it with the chopped vegetables.
Add in 1 tablespoon of poppy seeds.
Pick a large whisk or spoon and mix both of the mixtures well until evenly coated.
Your Colorful Coleslaw is almost ready; taste it in order to make sure it tastes good. Otherwise, you can season it with more lime juice, salt, and black pepper, if required.
Cover the bowl of Colorful Coleslaw with a plastic wrapping sheet and place it back in your refrigerator for at least 30 minutes to marinate well.
Serve it at the end of 30-minute marinating and enjoy some nice comments from your guests and family members.
Note: You can keep Colorful Coleslaw in your refrigerator and use it for at least two days.
