One of the cheesiest days of the year: It's the International Day of the Nacho!

My son said: "Dad, once I reach 99 pounds, I will eat one pound of nachos.'

'Then I will be 99% your son and 1% nacho son.'

The International Day of the Nacho takes place on October 21, according to nationaldaycalendar.com.

The day pays homage to the delicious dish and the man behind its creation, said the website.

Nachos were created in 1943 in a small town in Mexico called Piedras Negras which is right across the border from Eagle Press, Texas.

U.S. military wives were in town and visited a restaurant owned by Ignacio "Nacho" Anaya.

Needing a quick snack for the women, Anaya fried tortillas and topped them with melted cheese and jalapeños.

The cheesy dish made its way across the border to Texas where it became super popular in the 1970s when the Texas Rangers baseball team served it at Arlington Stadium.

Eventually, nachos were seen around the world with different countries taking their own spin on it, said the website.

Some notable versions of the nacho include:

• Greece- Substitute tortilla chips for pita chips and top with feta cheese, cucumbers, red onions, and tzatziki sauce
• Jamaica- Use their legendary jerk pork
• India- Substitute tortilla chips for toasted naan topped with curry powder and mozzarella cheese

Most popular toppings for nachos include:

• Beef
• Black olives
• Refried beans
• Grilled corn
• Onions
• Pico de Gallo
• Avocado
• Sour cream
• Lettuce
• Jalapeños
