I am keto, my girlfriend is gluten free. We eat veggies , and proteins. A standard meal will be a steak, chicken, pork, a veg side, zucchini, squash, cabbage, brussel sprouts. And a salad. I cook on the fire or stove.
As a example: 1)Last trip dinner one night grilled pork chop, I dry brined it in the morning. Veggie foil pack. Foil with a coupled pieces of bacon first with onion, red cabbage, tomatoes, cauliflower, zucchini , tomato’s paste, (from a tube), some basil, oregano, rosemary, Worcestershire, salt and pepper, and cheese Wrap and put over the fire indirectly cook and finish with balsamic vinegar. Salad.
Another night 2) Steak, red cabbage and apples, cucumber salad. Steak cooked in a frypan in. good bit of oil. 9 this will brown it up well, cover with foil while cooking. Red cabbage and apples, onion sliced and sautéed, add the thin sliced red cabbage and apple ( I grate mine to speed up cooking). Add vinegar and stir really well, most will add a bit of sugar now, we skip this. Add garlic, nutmeg, clove cinnamon, and cook till tender. Cucumber and onions sliced thin and put in to you favorite dressing, I do this first so it has a bit of time to combine while make the rest do dinner.
I will cook most anything on the road that I would cook home. I don’t prep a home, and most meals are a product of what I have on hand. Cauliflower, cabbage, brussel sprouts, broccoli, radish, squash, cucumber. green beans will last longer than leafy greens so I eat them first, pre-done salads will last for about a 4 days stay away from iceberg lettuce. If you use a 1/2 of a veggie on using the other half the next night. Cherry style tomatoes are easier to use because you can just use what you need. If you wrap the veg. in clean news print it will last longer, paper towels will work in a pinch.
You can always add rice or potatoes if you want starch. Rice is 1.5 or 2 times water to rice ratio, it’s on the package. Cook for 16 to 20 mins at a low simmer. Potato’s have a million ways to cook.
