How can I collect vitality restoring items like raw meat quickly and in volume?

I'm playing The Witcher 3: Wild Hunt in Death March, and I'm in sore need of goods like raw meat, dried fruit and milk.

How do I get these supplies without going through the hassle of looting individual buildings and fighting hordes of wolves?

Vitality restoring goods like Raw Meat and Milk are essential for the higher difficulties, since meditation doesn't restore vitality.

Here is a way you can never run out of such goods, while making a grand profit from hides.

Step 1: Find a spawn location for animals like goats or deer.

Step 2: Move away from the exact spawn location while keeping yourself in a place from where you can properly throw a bomb.

Step 3: Meditate to ensure spawning of animals.

Step 4: Throw a bomb at the location, and collect the loot.

One such spawn location I discovered, is to the left side of Fyresdal in Skellige:

Also, you can take Ekhidna Decoction to regenerate 10% of HP for each sign used.
