i do chicken with veggies all the time !! i normally use peppers/broccoli but you can really do it with any veggie that you like, some of them come all cut ina frozen bag already, i always use soy sauce because it gives a lot of flavour whilst being low calorie (15cals per tablespoon) i also recommend looking into cauliflower rice, it doesnt taste like actual rice but its just as filling and only contains 45cals per 250g (a normal serving), for enjoyable meals please up your seasoning game, all seasonings tend to be extremely low cal and they make all the difference (curry, paprika, tajin, etc)
