DO-AHEAD TIP: Marinate pork overnight or for at least 30 minutes (see recipe).
In a large zipper-topped plastic bag, combine 2 teaspoons of olive oil, the
lemon juice, garlic, chili powder and oregano; add pork strips, seal bag and turn to coat; refrigerate
overnight or for at least 30 minutes.
Heat remaining oil in a large skillet over medium-high heat; add onion and bell peppers and sauté
until tender-crisp.
Add pork strips and stir-fry for 3 to 7 minutes or until cooked through. Add tomatoes and stir-fry for 1
minute.
Fill warmed tortillas with meat/vegetable mixture and garnish as desired.
