Why don't you start making the food in your home, and selling it to small stores, construction sites, diners, etc.?
My mother started baking cakes at home and bringing them to restaurants to sell. She didn't have a business license, she didn't have any experience. (She also didn't have any health inspections, etc.) The start up costs were the ingredients.
Here's how she did it.
She started with one recipe - a cheesecake. She cooked a few cheesecakes, then went to a couple of different diners and high-end restaurants. All of them said no. So she told them to keep the cake, eat it themselves or sell it if they wanted and that she would return the next day to pick up the cake plates. She also took out a piece of paper for them and showed them the math. Split the cake into x pieces, sell each piece for $x. Whole cake sells for $x, pay my mom $y each cake. As long as you sell 1/2 the cake pieces, then the restaurant makes money for NO EFFORT.
On the second day, when she picked up the plates, every single restaurant asked for more and started (very loose) business agreements with her. It was basically a cash business. As soon as the restaurants realized how easy it was for them, they started asking what else she could bake. After the first month or so, she had 5 or 6 items that she made for 7 different restaurants. She delivered some pretty fancy desserts in our family station wagon!
It was incredibly difficult though, especially because she didn't have a commercial kitchen.
So I would start at home, under the counter, see if you like it, and see if people like what you're making. If you find someone that likes what you make, you may be able to work out a deal to use their commercial kitchen in off-hours to pre-make some food.
Lots of different ways to get started without jumping into starting a new business with which you may not yet be prepared.
