Step 1

In a blender or food processor, place the garlic, chili powder, paprika, chipotle pepper, pineapple juice, vinegar and 1/2 cup of the pineapple chunks. Puree until smooth, 1 to 2 minutes.

Step 2

In a large skillet over medium-high heat, add the onion and beef and cook, breaking it up with a wooden spoon until the meat is no longer pink, about 10 minutes.

Step 3

Bring the heat down to low and add the pineapple sauce, remaining cup of pineapple chunks ( I like to dice these a bit smaller), and jalapeno. Simmer for about 10 minutes until the sauce is reduced and coats the beef. Taste and season with salt if desired.

Step 4

Remove from heat and fold in the shredded cheese and cilantro. Serve with the warmed tortillas and toppings.
