I dont travel with a motorbike but I have travelled together lots of times with bikers in Africa & Central America.
What I think is that the lack of cooking gear limits the bikers' choices.
On my side and travelling with a campervan, we have lots of options but I prefer to travel minimal which is translated to one pot, one pan, 4 plates and loooots of spices.
Cooking in the camping is a matter of time but also a matter of available resources and cooking gear. If there is a super market nearby or you can shop before camping, then you can do amazing things. However, my suggestions & ideas will me limited to what you can carry full-time or shop and carry for 1-2 days.
This is what you can make with
one pot/pan, one plate & one stove and what I have seen other bikers cook:
Breakfast/Lunch
- oatmeal (its always easy to carry a small bag of oats or a mix trail with nuts & raisins and a long-life milk or just water)
- scrambled eggs (with sausages)
- boiled eggs with some tomatoes & sausages
- warm up beans from a tin can
- In North, Central & South America you can find also oat powder (plain or flavored) which can be mixed with water or even better with milk and keep you full until your first break.
- cereals with milk (you can always carry a small bag of cereals)
Lunch/ Dinner
- omelette with eggs, chopped tomatoes, green pepper & sausages
- any type of pasta with any sauce (if you like ready-made mixes of sauces you can go for it). Instead, you can boil the pasta and chop fresh cut tomatoes, green peppers, onions, mushrooms (the more veggies you can find available, the better) and some oil. Its super healthy, hand made and not monotonous at all. Another variation is stir fry mushrooms first, put them in your plate, boil the pasta and then pour milk cream and the mushrooms. If you can add bacon, then you have a proper carbonara in the outdoors.
- any type of rice with veggies (chicken). You can sauté veggies and meat and then put them back in your plate. Then you boil the rice and you mix the veggies and chicken. Another variation is the same recipe but with chinese noodles.
- With the help of a grill plate on top of your stove, you can literally cook any type of meat, veggies, eggs relatively fast and of course tasty. Basically, you can do miracles with just a light aluminum coated grill plate on top of your camping stove.
In general, everything depends on the availability of food you can find taking into consideration that your carry-on capacity is limited. Fresh veggies is your best choice and are wide available literally everywhere. Rice & pasta are also wide available in Africa, Americas & Asia. Meat is a grey area and depends on the hygiene conditions (if not available in a western-type groceries store) but fresh cut chicken is also available almost everywhere.
To be really honest and as mentioned before, without being a biker but only having spent time with travellers on motorbikes, I see it quite difficult (but not impossible) to set up your cooking gear & cook all these things (especially my sort of recipes/ ideas for lunch/ dinner) after a looong muddy/ rainy/ dusty/ windy travelling day. If in the middle of nowhere and assuming that you did your shopping before starting maybe you can.
I have seen lots of bikers to eat out especially the night they arrive at their destination but cook the next days if they stay in the same place.
The problem I see is the location (where are you camping, if it is windy-rainy etc), the carry-on capacity (which is always limited compared to cars), the time available (if you arrive early or late), the cooking gear (some people on vans even have a pressure cooker which is at least unfair if you compare it with the gear a bike can carry) & the available supplies you can get along.
I will be happy to hear real stories from bikers with a rich recipe camping book!
