Place a Caldron or Dutch Oven on medium-high heat, add 1 tablespoon of oil to the metal skillet, once heated add corn, minced green bell pepper, minced red bell pepper, minced jalapeño pepper, Spanish onions, and 2 minced cloves of garlic, sauté for about 2-3 minutes to soften before removing from heat-reserve.
Next add low-sodium vegetable broth to the Caldron or Dutch Oven with veggies from above high heat to bring to a boil, then add diced tomatoes with chiles, oil, Sazon seasoning, dried oregano, cumin, cayenne pepper, kosher salt, freshly ground black pepper, and long grain rice cook on high about 2-3 minutes stirring a few times, cover with a tight-fitting lid and reduce heat to low. Cook on low heat about 14 minutes.
Turn off the heat source and let the rice sit undisturbed and covered about 5 minutes before fluffing the Mexican Rice with Corn with a fork.
Sprinkle rice with the juice of 1 lemon and garnish with chopped cilantro if desired.
