Currently I'm carb cycling (High, Low, No), I've been getting creative on the no carb days (actually around 35g carb) with my proteins and have a few good mixes/prep techniques to pass along.
London Broil- Remove all fat, then spice with paprika, salt, and pepper. Then lightly spray Pam on the meat, repeat on the other side. After that, cook on med-high heat in a non-stick frying pan (you don't need to spray the pan with non-stick spray as it is already applied directly to the meat). Make sure to COVER the pan while cooking with a plate or baking sheet so no steam escapes, this will really make the steak turn out better. TIP: After using the 3 spices and nonstick spray, lightly rub everything into the meat before cooking.
Chicken Breasts- Pretty simple, remove any excess skin/fat/connective tissue, then marinade the chicken for a day in apple cider vinegar (you may want to dilute it with 1/3 to 1/2 part water), after that throw it on the Foreman Grill (don't forget the non-stick spray).
Egg white "omelette"- This is my favorite one, most of us cook in bulk to save time (either daily or weekly), with that being said I have London Broil and Chicken on hand (prepared as mentioned above). Spray a non-stick pan with some Pam, add your egg whites (I like Better N Eggs/Egg Beaters) then throw in some pieces of steak and chicken, allow to cook for a few minutes then flip it over to cook the other side, bam you have a great tasting protein loaded, near 0 carb omelette. I especially like to make these because they incorporate 3 different protein sources and as you probably already know each of those sources differ in rate of time it takes the body to process and retrieve amino acids from (egg ~3 hours, chicken ~ 6 hours, steak up to 24 hours).
Enjoy
