Mix the garlic, ginger, 1/2 cup cilantro, and sunflower oil in a large bowl.
Add the pork, cover tightly and refrigerate for an hour or overnight.
Heat a deep skillet over medium heat, add pork with marinade, and stir frequently, cooking pork through completely, 7-10 minutes.
Remove the pork with a slotted spoon and keep warm.
Add coconut oil. When melted, add onions, cooking for about 3 minutes or until slightly translucent.
Add bell pepper and cook for another 3 minutes, until crisp-tender.
Return the pork to the skillet, adding lime juice, remaining cilantro, salt, and pepper.
Cook until heated through, remove from heat, cooling slightly, and serve over mixed greens.
