Line a cookie sheet with aluminum foil and add bacon
Bake bacon in the oven at 370 degrees for 20 minutes or until done.
While the bacon is in the oven start preparing the brussel sprouts.
Take off the outer leaves, cut off the stem from the bottom of the brussel sprouts and slice the brussel sprouts in half. If they are miniature size, don’t slice and keep whole.
Rinse the brussel sprouts with cold water.
On medium heat, add olive oil to a large non-stick skillet; or you can use the bacon fat from the cooked bacon.
Add the minced garlic and simmer for 1 minute.
Add the brussel sprouts to the skillet and stir to coat with the oil.
Depending on your palette, add onion powder or diced onion.
Stir in the remaining seasonings - rosemary, salt, and black pepper.
Cover the skillet and cook the brussel sprouts, stirring occasionally, until tender for about 10 minutes.
