Preheat oven at 375. Slice corn off the cob and add to a mini cocotte. Melt butter and add to the cocotte, along with lime juice. Cook for 10 min. Remove and let cool.
In a medium pan, heat up olive oil and ¾ of the jalapeño (sliced). Cook for about 15 min on low and then drain and reserve oil.
Depending on how many beans you want, you can cook the beans together or in 2 separate cocottes. For a can of each, you will need more than one cocotte. Divide oil between cocottes and beans and bake for 12 min. Remove and let cool.
Make dressing and dice all ingredients and add to a large bowl.
If you are making homemade tortilla chips, add oil to a Le Creuset dutch oven and when it's hot, add in sliced tortillas. Cook until golden brown. Remove and add to a paper towel. Enjoy!
