In a large bowl, toss together beef and dry spices.
Lightly coat a 4- quart stockpot with olive oil spray; heat over medium-high setting.
Sauté beef on all sides until evenly browned, about 2 minutes.
Stir in beef broth. “Deglaze” the pan by stirring constantly (at medium-high heat) while loosening any brown bits stuck to the bottom.
Remove beef and broth mixture to a bowl.
In the same pot, lightly coat again with olive oil spray; heat over medium-high setting.
Sauté onion, garlic, peppers, jalapenos and ginger for about 5 minutes or until vegetables are tender.
Stir in tomatoes, vinegar and reserved beef and broth.
Cover; simmer over medium-low setting for 45 minutes to 1 hour or until beef is very tender and falls apart. (Do not let boil.)
Remove beef from pot and shred with a fork; return to pot to keep warm.
Garnish with chopped green onions and cilantro.
