In Alma 8:22
And it came to pass that Alma ate bread and was filled; and he blessed Amulek and his house, and he gave thanks unto God.In Alma 34:21
Cry unto him in your houses, yea, over all your household, both morning, mid-day, and evening.We have one example of a prayer after the meal and one admonition to pray three times a day. Both of these verses are in line with Jewish tradition and practice. Jews say grace after meals (https://www.hebrew4christians.com/Blessings/Daily_Blessings/Food_Blessings/Grace_After_Meals/grace_after_meals.html) and they are expected to pray three times daily (https://www.chabad.org/library/article_cdo/aid/682091/jewish/The-Three-Daily-Prayers.htm)
