Cook the sorghum grain using 2 cups of the water in a pressure cooker (@ High Pressure for 1 hour). While the sorghum is cooking, prepare the other ingredients. Using a medium-sized pot, start sautéing the minced garlic and onions in olive oil. Add the corn, all peppers, cilantro, tomatoes, salt, and lemon pepper. Continue sautéing (to remove water) for about 10 minutes on medium heat. Add cooked sorghum into the pot and stir gently to combine all ingredients. Cook for an additional 10 minutes on low-medium heat.
