I like to choose a selection of veg (as low or high carb as you want) but I go for peppers/aubergine/onion/broccoli, I chuck it in an oven dish and drizzle with olive oil, pepper & salt, and any herbs & spices you wish. Cook for around 30/40 minutes and the vegetables turn into a smoky, buttery, lovely taste, GREAT to have with any piece of meat or fish, especially salmon, and VERY easy. Count the carbs of the veg you use if you are sticking rigidly to under 20 carbs though. I find this addition to meat makes a very low carb and satisfying meal. Oh, and I may use a blob of mayonnaise too (low carb if you wish).
