Some cravings are about more than flavour. It’s the crunch, the layers, and getting a little bit of everything in every bite.

The Guac Crunch is grilled, loaded and made fresh with the bold flavours you know and love.

Now the real question: how many bites before you’re thinking about your next one?

Back to school means:

Earlier mornings.
Busier evenings.
Practices, homework and pickups.
And dinner still needs to happen.

Guac makes one part of the night easier.

Burritos. Bowls. Tacos.
Fire-grilled proteins.
House-made sauces.
Built your way.

Something everyone can enjoy.
One less thing for parents to figure out.

Bold Flavour Starts Here.
