The cost of a standard meal in my country depends on where you are having the meal, which is your location. So I will give cost for comparison under a well packaged restaurant where you can buy and eat your food there, and then a road side food vendor, where you just buy your food and take it home.

I will use our popular menu white rice and Chicken Tomato stew, spaghetti and then Beans, soft drinks which are common meals and drinks in the menu of the well packaged restaurants and the road side vendors.

Well Packaged Restaurant
Cost of a plate of white rice and Chicken Tomato stew - $6.23
Cost of a plate of Spaghetti and a protein of your choice - $6.23
Cost of a plate of Beans - $1.12 per portion, the more portions you need, the more the price.
Cost of soft drink - $1.25

If someone buys food three times daily for 30 days (3 x $6.23 x 30), that is a total of $560.7 which means that you have to be earning way more than the minimum wage to afford three meals a day for thirty days in a well packaged restaurants.

Road side food vendor
Cost of a plate of white rice and Chicken Tomato stew - $1.25
Cost of a plate of Spaghetti and a protein of your choice - $1.25
Cost of a plate of Beans - $0.37 for a small size, price increases if you want more.
Cost of soft drink - $0.31

If someone buys food three times daily for 30 days (3 x $1.25 x 30), that is a total of $112.5, which is above the minimum wage, so someone who earns the minimum wage or less will not be able to afford three meals per day for days, they will have to starve on some days.

Minimum wage as at 1st September 2023 was increased officially from $41.10 to $80.95 on paper, but some people are still receiving the old rates of $41.10 and some even less than that because some employers do not care about minimum wage.
