Cinco de Mayo is coming — a day where guacamole, margaritas and Mexican food galore can pack a scary number of calories!

Not to worry: Whether you’re heading to a party or planning a PJ-clad party of one (the holiday is on a Monday this year, after all), you’ve got plenty of great guilt-free options.

Party Eats: Supersized Guac and Chips

This guacamole recipe is amazing. What makes my guac so much lower in fat than others? I expand the portion size with mashed peas! Yes, avocado is full of healthy fats, but you don’t need to eat a lot of it to reap the benefits. (Plus, you won’t really taste the peas in the mix.) Easy-to-make, baked-not-fried tortilla chips seal the deal.

Party of One: GoodFoods Tableside Greek Yogurt Guacamole with Guiltless Gourmet Yellow Corn Tortilla Chips

This guac comes in li’l tubs for portion-controlled perfection, with just 70 calories and 5g fat each. It’s also lightened up with Greek yogurt — a company after my own heart! The chips are another grab-n-go favorite of mine. Just portion them out ahead of time…

Party Eats: Exploding Chicken Taquitos

Those frozen taquitos you can buy by the boxful? They’ve got way more fat than necessary, and they’re typically tiny! This recipe, on the other hand, makes large taquitos with only around 1 gram fat each. Your party needs a batch of these!

Party of One: Evol. Snack Size Mini Burritos

One of these petite burritos is a perfect pick for a solo Cinco celebration. Choose from Bean & Cheddar or Chicken, Bean & Rice. Each has 180 calories and 5g fat. Grab some hot sauce or salsa, and go to town!

Party Eats: Sinless Margarita Mix

Shortcut alert: For speedy slimmed-down margaritas, it’s all about the low-calorie mix. This bottled mixer is made with stevia and has a mere 5 calories in each 3-oz. serving — just add tequila, and serve it over ice. Too easy.

Party of One: HG’s Magical Low-Calorie Margarita

I do make my magical margarita by the pitcher for parties (always!), but the recipe is for a single drink. So if you only need one, just make one. Otherwise, feel free to multiply the amounts by however many pals are coming over… which might be all of them, once they find out what you’re making!

‘Til next time… Chew the right thing!
