As 2020 drew to a close, Taco Bell deleted over a dozen items from its menu, including fan favorites like potatoes and the iconic Mexican Pizza.

While potatoes are back on the menu now, the rest of the lineup slots look like they might be filled by some test items Taco Bell has run. There's a lot being trialed right now, including the addition the viral Chicken Sandwich Taco that's sparked some roasting from fellow fast food chains.

In total, Taco Bell has over a half dozen items testing right now. One set of items, pictured above, is the new "Primo Burritos," currently testing in Kansas City. There's no clear distinction as to what makes these "Primo," although it appears the model for these is "look weighty but be on a budget."

The two versions, Loaded Taco and Chicken Enchilada, cost no more than $1.50 each (the Loaded Taco one being just $1), and are packed with sour cream, rice, cheddar cheese, and ingredients that give each burrito their distinct flavor.

Stackers are also making a reappearance, this time in Grilled Cheese form. Taco Bell didn't provide any details on this item other than the name, but it looks like the tri-folded quesadilla may come with a cheesy crust, as the Grilled Cheese Burrito of old did. This item is currently being tested in Houston, Texas.

Over in Columbus, Ohio, Taco Bell is looking at tacos that are all about the heat. This set of $1 Spicy Tacos feature the chain's proprietary beef, lettuce, cheese, and one of three different spicy sauces. Customers can opt for Mild Jalapeño, Medium Chipotle, or a "White Hot" Ranch made with ghost chili peppers.

Portland Taco Bell fans can try out a new trio of bowls currently being tested in the area. Called the "Stacked Bowls," each comes with a double portion of meat. From there, ingredients may vary, with seasoned rice serving as a base, but other ingredients like refried or black beans, a variety of sauces, or even a new purple cabbage topping all available.

The Stacked Taco Bowl contains beef, rice, refried beans, a blend of purple cabbage and lettuce, crunchy red strips, a three-cheese blend, sour cream, tomatoes, and guac. There's also the Avocado Ranch Chicken Bowl (chicken, seasoned rice, black beans, a blend of purple cabbage and lettuce, a three-cheese blend, and avocado ranch sauce) and a Stacked Steak Melt Bowl, which goes double on both steak and cheese with rice, crunchy red strips, black beans, tomatoes, and chipotle sauce.

The bowls are the most expensive new item being tested, costing $4.49-$4.99 each.

Outside of the plethora of new test items, Taco Bell also dropped a new Strawberry Lemonade Freeze nationwide. The new slushy beverage is made with what the chain describes as "wild strawberries" and lemonade, and is available for a limited time.

Taco Bell is clearly looking to stack their menu with a variety of new options, but we'll have to see which of these make it out of the test locations and into nationwide launches.
