Answered: Isekai Cheat Suvival Meshi

I forgot an isekai manga i read some time ago, it was about a teenage guy who gets isekai'd (i think by truck-kun) finds himself in the middle of a jungle/forest whatever it is. Anyway he's actually a bit glad with his current circumstances since he likes camping and cookouts. He then meets this girl who apparently uses magic but her injury is too much for her to heal in a single day, so he takes her to his cmap and treats her to food. He discovers he gets abilities from the ingredients he cooked and finds ways to utilize it to his everyday jungle life survival...some time later they get threatened by a huge animal that looks like a deer with a huge body and huge antlers, a loli with a huge sword comes by and lends him the sword, he kills the animal then he successfully gains an ability from it and also takes in the loli swordswoman in a nun habit-ish clothes and feeds her too.
