Place chili peppers in pot and toast over medium-high heat. Add 2½ cups chicken stock and 1 cup water, bring to boil, reduce heat and simmer to reduce liquid by about half and soften chili peppers, about 8-10 minutes. Once tender, puree in food processor or blender with honey or agave to lightly sweeten.
Meanwhile, in a second saucepot, heat 1 tablespoon butter and add rice. Toast the rice until fragrant, about 4-5 minutes. Add remaining stock and bring to a boil, add salt and cook about 13-15 minutes. Add corn and peas, cover, and cook 2-3 minutes more. Remove from heat and let stand 5 minutes; adjust salt, then fluff with fork.
For the chicken, in a large skillet over medium to medium-high heat, melt remaining butter, add onion and garlic, salt and pepper and lightly brown and soften, 5 minutes. Add spices and oregano and stir a minute, then add chicken and combine with sauce to heat through. If chicken gets dry, add a little more stock or water. Add juice of 1 lime to serve.
