What started off as a small test has turned into a possible addition to Taco Bell's nationwide menu — the Waffle Taco.

Egg and sausage wrapped up in a fried waffle first appeared on menus across five different restaurant locations in Southern California last March. Conveniently priced at $0.89, the breakfast item was a hit with early morning customers.

"We're pleased with the initial reaction from our customers and if the Waffle Taco does well in testing, we'll roll it out to all our restaurants that serve breakfast," spokesman Rob Poetsch said in a statement.

Currently 850 locations in 10 western states already offer a breakfast menu where the Waffle Taco hasn't been the only exploratory item. On Thursday, a full breakfast menu featuring the Waffle Taco will be brought to 100 locations in Fresno, Calif., Omaha, Neb., and Chattanooga, Tenn. Taco Bell will also be testing a yogurt parfait and oatmeal, the Associated Press reported.

At 460 calories and 30 grams of fat, the Waffle Taco doesn't rank well among the healthiest breakfast options that one should consider. If you are looking for a more nutritious alternative during that morning on the go, consider the following:

1. McDonald's Fruit & Maple Oatmeal - One of the only items on McDonald's full menu that offers fruit, oatmeal is an essential part of any healthy diet. Without brown sugar, this morning snack weighs in at 260 calories, 4.5 grams of fat, and 7 grams of protein.

2. Dunkin' Donuts Egg White Turkey Sausage Wake-Up Wrap - Containing egg whites, spinach, turkey sausage, and reduced-fat cheddar cheese, Dunkin' Donuts' morning wrap is your best choice in a world full of glazed and jelly-filled fried dough.

3. Subway Western Egg White & Cheese Muffin Melt - The pioneer of healthy fast food does it again with its egg white and Black Forest ham sandwich. Including peppers, onions, and Monterey and American cheese, this morning delight will only set you back 160 calories and 4 grams of fat.

4. Starbucks Protein Artisan Snack Plate - True to its name, Starbucks' variety breakfast platter is packed with 13 grams of protein. The downside? It comes with 370 calories and 19 grams of fat.
