Low Carb On The Border Options for Keto Diets

Dallas, Texas is ground zero for Tex-Mex, so it should come as no surprise that the city is where On the Border got its start. Way back in 1982, three friends has a vision to bring fresh, handmade Border-style cuisine to as many people in the world as possible. Tequila may or may not have been involved in the dream phase of this exuberant scheme, but their idea caught on. Today there are more than 160 locations in 33 states, Puerto Rico, and even such far-flung places as Egypt, the Mideast, and South Korea. Famous for its mesquite-grilled fajitas, On the Border is the world’s largest Mexican fast-casual chain.

Before we get to the menu, a brief explanation of Border-style food. Tex-Mex is more than just Mexican food made in Texas. The cuisine developed out of the Tejano culture (Quick history lesson: Tejanos are Texans of Spanish or Mexican heritage who were living in Texas before it gained its independence from Mexico and joined the U.S). What are the main ingredients that separate the two? Beef, yellow cheese (such as cheddar), the spice cumin, canned vegetables (tomatoes in particular), and wheat flour. So if your meal contains any of these ingredients, it’s probably Tex-Mex.

Fajitas are a great example of Tex-Mex. ‘Faja’ means ‘strip’ in Spanish (as in ‘a slice of meat’), and the recipe is inspired by Mexican ingredients, but the wheat tortillas give it away as a north-of-the-border invention.

Chili con carne is considered a quintessential Tex-Mex dish, but guess what? The ingredients mostly come from northern Native American recipes, not Mexican. So much for that.

Between the nachos, beans and rice, Tex-Mex doesn’t seem like the kind of place keto eaters would want to venture into, but there are plenty of things that are safe to order. On the Border’s nutrition information is available online, but we’ve got all your keto picks right here.
