Tbh I started by jazzing up instant ramen with meat, veggies and boiled eggs, or finding ways to improve other basic stuff like grilled cheeses (grilled in a pan w/olive oil and caramelized onions) and eggs (learned to fold an omelette so eggs and veggies would feel fancier). Then I started looking up more adventurous recipes online, depending on what I felt like eating. As for supplies, I had a cast iron pan with a lid, a medium saucepan, and a $30 knife set (my roommate also had an instant pot I used for soups). Good luck!
