In the bowl of a food processor, add the tomatoes, lime juice, jalapeño pepper, onion, cilantro, cumin, chili powder, salt, oregano, and pepper.
Pulse until blended but still a little chunky.
Refrigerate until ready to assemble the burritos.
Avocado Crema
In the bowl of a food processor, add the avocado, sour cream, mayonnaise, lime juice, salt, cumin, and garlic powder.
Pulse until smooth.
Refrigerate until ready to assemble the burritos.
Carne Asada
To a 1/2 gallon plastic bag, add the olive oil, soy sauce, lime juice, sugar, cumin, garlic powder, paprika, salt, and pepper.
Add the steak to the bag and seal it. Massage the meat to coat completely. Place in the refrigerator to marinate for 4 to 8 hours.
Remove the steak from the refrigerator 30 minutes prior to grilling. Prepare your charcoal or gas grill. Or, preheat a grill pan to medium-high. Grill the steak 5 minutes per side, or until an internal thermometer reads 130°F.
Transfer the steak to a clean cutting board. Tent with foil and allow it to rest for at least 5 minutes.
Slice the steak thinly against the grain.
French Fries
Preheat your oven to 400°F. Line a baking sheet with foil.
In a large mixing bowl, combine the olive oil, cornstarch, salt, and pepper.
Slice the potatoes into 1/4-inch thick strips or fries. Add them to the bowl and toss to coat evenly.
Place the fries in a single layer on the lined baking sheet.
Place the pan in the oven and bake for 15 minutes. Turn the fries over and continue to cook for an additional 15 minutes until golden brown and crispy.
Burritos
Warm a skillet or flat top griddle over medium heat.
Place the tortillas on a flat work surface. Layer each tortilla with carne asada, followed by French fries, cheese, avocado crema, and salsa. Roll the burritos tightly.
Warm the burritos on the skillet or griddle just until the cheese melts, rotating once to brown both sides.
