Carefully slice the tough outer skin off the broccoli stems. (If you look at a cross-section you can see the 1/16th in. skin.)
4 Large Broccoli Stems
Grate the carrots and broccoli stems (I recommend using a food processor or electric shredder).
Put the sugar in a medium bowl and add the vinegar. Stir for a minute to allow the vinegar to begin to dissolve the sugar.
2 Tablespoons Granulated Sugar, 2 Tablespoons Apple Cider Vinegar
Add the mayo, ground mustard, salt and pepper and stir.
1/2 Cup Mayonnaise, 1/4 teaspoon Ground Mustard, Salt and Pepper
Mix in the veggies and chill before serving. Top with sliced almonds if desired.
Almonds, 1 Cup Raisins

Notes
You can also buy a bag of broccoli slaw at the grocery store and skip shredding the broccoli stems and carrots yourself. Broccoli slaw usually comes with shredded carrots and sometimes red cabbage.
