Roast bacon on a sheet tray at 400° for approximately 15 minutes or until bacon is crispy.

If you do not have a roasted sweet potato, then either dice and boil a peeled sweet potato until fork tender or rub a tiny bit of vegetable oil on the unpeeled sweet potato and wrap in foil. Pierce with a fork several times to allow steam to escape.

Combine the sweet potato, butter, sugar, milk, and a pinch of salt in a mixing bowl and mash to incorporate.

Toss arugala and poppy seed dressing in a mixing bowl.

Spread mayonnaise on the bottom of each cut bagel, and honey mustard on the tops.

Add dressed arugala and avocado. Assemble sandwich.
