kiss the chef
You've made dinner at home before, but when was the last time you explored some unique or new recipes together? Or maybe you just want to show off, or have some fun in the kitchen with something (or somebody) way out of your league. Either way, this date is perfect!
These two sites have some amazing recipes to choose from:

https://www.delish.com/holiday-recipes/valentines-day/g4640/easy-dinner-recipes-for-two-for-beginners/
Choose a recipe you want to try. If the amount of choices is overwhelming, here's a random number generator to help out (no cheating if you use it, respect the results).
Once you have your recipe, go together to buy all your ingredients from a local grocery store like The Market (Herndon & West). Then go back home and make and eat the recipe together.
Have fun with it and play some music while you do it. Have a food fight if you'd like. This date is all about fun and exploration, so have a blast with it!
