In a large skillet or paella pan, heat 2 tablespoons of olive oil over medium-high heat.
Add the onion and bell pepper, cooking until softened for about 5 to 8 minutes.
Stir in the garlic and cook until fragrant, approximately 1 minute.
Remove the vegetables from the pan and set aside.
Add the remaining olive oil to the pan.
Season the chicken pieces with salt and pepper, then add them to the pan.
Cook until they are about 50% done, ensuring they brown nicely.
Remove the chicken and add to the reserved vegetables.
In the same pan, toast the bomba rice for about 3 minutes.
Mix the chicken broth with the Paellero seasoning, then stir this mixture into the rice.
Return the chicken and vegetables to the pan.
Pour in the diced tomatoes and 1 cup of water.
Let the mixture simmer on medium-low heat for 20 to 25 minutes, or until the rice is tender and the liquid has been absorbed.
If the rice remains too firm, add more water or broth as necessary.
Stir in the peas and parsley, cooking for 1 to 2 minutes until warmed through.
Adjust seasoning with salt and pepper if needed.
Garnish with lemon wedges before serving immediately.
