What I've learned is to collect some easy recipes and have some basic cooking tools handy to make it easier to cook fresh.
Tools:
Basic set of knives, steak, paring, mid-size serrated, chef and/or santoku knife (I highly recommend the santoku for veggies, but before I got it I made due with a mid-size serrated knife)
Kitchen shears - makes cutting meat into bite sizes so easy (don't know how I went years before recently getting one of these...)
Pot/pan set - small pot for hot cereal, medium for most others, frying pan, larger pan with lid
Basket for steamed veggies - it's a foldup metal thingy that you put in you pot to assist with steaming veggies
Crockpot
Cookie sheets for oven baking stuff
I started acquiring my cooking items via garage sales and still use a lot of them a couple decades later. Then slowly I upgraded when Christmas gift suggestions and saving for specific items.
Cooking tips:
For steaming veggies - I put my metal steamming thingy into the pan. Either buy pre-cut veggies or slice them up myself. Fill the basket, add water to the base of the basket (roughly), then place on the stove on med-high heat. Once I hear the water boiling, I'll let them steam about 5-10 minutes depending on the veggies. Adjust the steaming next time based on if the veggies were too crunchy or soft for your taste.
Easy Pork recipe (Maple Pork and Apples):
Need larger flat pan with lid. If you don't have a lid, find something to improvize (like a similarly sized pan turned upside down or a baking dish.
4 pork chops, 12 mini carrots (I use a few more), apple (sliced to bite size, seeds removed), 1/3 cup maple syrup (try to spring for the real stuff), 2 Tablespoons of butter.
Melt butter in pan. Season both sides of the pork chops with salt/pepper. Brown them in the melted butter for 2 minutes, about a minute each side. Add the sliced carrots and apple. Add the maple syrup. Cover, reduce heat to simmer for about 8 minutes. Remove pork chops, carrots and apples. Increase heat to boil down the "sauce" - making it a little thicker, and pour over chops.
This makes dinner for me for 4 days (as I live alone).
And here's an easy stew recipe for the crockpot:
1-2 pounds of meat (stewed beef chunks, chicken, turkey)
2 carrots
2 potatoes
mushrooms (optional)
1 onion (I use half)
1 celery stick
Garlic clove
Seasonings (basic salt/pepper or whatever else to taste based on the meat selection)
1-2 cups broth (appropriate for meat selection)
If needed, cut meat into bite sized pieces with kitchen shears. Place in crockpot. Season and add 2 tablespoons of flour. Mix to coat the meat evenly. Slice up carrots, potatoes, mushrooms, onion, celery and garlic. Add to crockpot. Mix everything thoroughly. Add 1-2 cups broth. Cover and cook on low 10-12 hours, or high 4-6 hours.
For the crockpot recipe, I'll buy mean on sale and freeze it in portions to make the stew. Most of the veggies last for quite a while. I've been having weekly stews, with the occasional maple pork chop this winter and still have enough frozen meat to last a couple more months. For me, this lasts me 4-5 meals.
I keep an eye out for easy recipies like these - few ingredients, nothing too fancy, and very tasty (in my opinion).
Hope these help get you going, or give you new ideas.
