I cook for one so a lot of extra meals, I will freeze most anything for a "second meal or two.
One of my favorite things to do is grill up a bunch of hamburgers and bag and freeze. Then when I need a quick meal, just thaw/heat in microwave for a minute or so and serve on homemade/freezer ready bun or serve alone with sides. The frozen bun will thaw in about 20 seconds in the microwave, so in less than 5 minutes I go from "want to eat"!! I go to Sams Club and buy the big package of 90/10 ground beef, weigh out 4-5 oz patties and cook all at once on the grill. Depending on the weight purchased, I get over a dozen burgers. My motto: If you are going to fire up the grill, cook a lot and make it worthwhile.
