Get about half a pound or a little more of meat per meal that you'll be eating meat. Meat was always the hardest one for me to figure out. It shrinks when you cook it, there is bone and other waste, so half a pound ends up less than that.
It's okay if you don't purchase the right quantities at first. You can always go back to the store to get what you forgot. You can always freeze extra meat. Stuff that's starting to get old can be cooked and then frozen and it'll keep longer that way.
Ask for a spice rack for Christmas. It's nice to have the labeled jars. Then refill the jars with spices from the health food store in the bulk spices department. It's a fraction of the cost of buying filled jars. Those bulk spices they now sell in the grocery store are actually way more expensive than the regular jars. Read the labels on spices because nowadays they are faking the spices with fillers and sugar and other fake stuff.
