Preheat oven to 350 degrees F. Add dry rice to a mesh sieve and rinse under cold water until water runs clear.
To a blender or food processor, add tomatoes, onion and approximately 2 Tbsp of the minced cilantro. Process until smooth. This should yield around 2 cups, but if there's excess, discard any amount more than 2 cups.
Add vegetable oil to a large, oven safe pan (I love to use my Le Creuset buffet casserole dish), and heat over MED heat. Add rice and saute for about 5-10 minutes, until fragrant and lightly golden.
Add garlic and jalapeño and stir about 30 seconds or so, until fragrant. Add tomato puree, tomato paste, chicken broth and 1 tsp salt. Stir to combine and bring to a boil.
Cover and bake about 25-30 minutes, until liquid is absorbed, stirring halfway through. Fluff rice with a fork, squeeze lime juice over rice and stir in cilantro and green onions.
Taste and adjust by adding more salt or black pepper, if needed.
