Some fat fast "meals" I like are:

2 thin slices of braunschweiger each spread with a tablespoon of mayo and a little squirt of mustard.

Cream cheese into which I mix some diced pastrami and onion. I serve that on a "cracker" of thin hard salami slices I crisp in the microwave for about 45 seconds.

Egg salad (hard boiled egg mixed with mayo) served in a lettuce-leaf.

Chocolate candy I make from coconut oil and butter: melt together 1 cup CO and 1 stick butter in the microwave, add about 6 T of cocoa powder (I mix equal parts regular and dark) and maybe 3 packets splenda. Pour into a plastic-wrap lined cake pan and freeze or refrigerate until hard. Break into squares and keep in the fridge. I try to size the squares so that each is about a tablespoon, so I can track the calories. Will depend on the size of the pan you used as a mold.

Coffee, to which I add 1T of CO and 2T heavy whipping cream.
