This recipe is very well presented and developed, we congratulate you for it.
However, remember that butter is not a vegan ingredient, as it comes from cow's milk. Margarine can be a vegan ingredient, as long as it is dairy-free. Next time, we would like to see the margarine components you use in your recipes in this community.
On the other hand, the cubes or cubes for seasoning are NOT vegan ingredients, as they include in their composition ingredients that may be of animal origin.
Keep these observations in mind for your future posts.
I am so sorry for not doing my research on the seasoning cube before using it. However, butter is a common name we call margarine here in Nigeria; what I used is actually margarine, and here is the picture of the remaining sachet of the margarine.
I will take note of the corrections
