Okay, let me break this down for you.
In Kenya we have different delicacies:
1. Ugali and Stew (Ugali is baked maize meal flour - tasteless - eaten with meat stew or vegetable stew)
2. Vegetable stew consists of greens such as cabbage, kales, free peas, potatoes of cause not forgetting tomatoes, onions, green pepper, cauliflower - a bit rare but available - coriander, different herbs and fresh bananas)
3. Meat - This is the trend, meat in every meal, but still if you are vegetarian, am sure no one will have an issue with that, Kenyans are cool they will put aside your food before the meat is added to the flavor.
4. Milk and bread with butter - this is the morning breakfast, add some eggs if you fancy but thats what the normal average Kenyan morning breakfast is comprised of.
5. French fries available for snacks at urban centers.
6. Rice, spagettini available. infarct there are many different food types, just depends on what you prefer, but I would recommend UGALI anytime

, its bound to challenge you BIG time.
