For years now, I keep thinking I'll get tired of it but my favorite BIABM is Ramen with freeze dried Vegetables and Chicken.
I crush the Ramen before opening the package. Put crushed Ramen into snack-sized baggie. Throw away the "flavor" packet. Add one crushed chicken bullion cube. Add an amount of Just Veggies, mixed, freeze dried vegetables. Add a third of an ounce of freeze dried chicken - or, for the first three days, a 3 ounce can of cooked chicken, including the broth. If using canned chicken I remove air from baggie, roll tightly, fasten with rubber band and freeze.
Variations of this use instant brown rice and, perhaps, curry powder, ground ginger, crystallized ginger, raisins, and sliced water chestnuts. Still adding the chicken.
I always look forward to eating this and only try changing it every few years. If I hadn't just finished a great barbeque dinner, from Gracie's, in Vallejo, I'd whip up some right now.
