I call this the Swiss Army Knife of savory dishes because once you've created the 'base' there are so many ways to customize this to what's in your pantry or what you like for dinner tonight!
In a large skillet on medium high heat, add the olive oil and then add the onions and jalapeno. Saute until the onion has turned translucent. Add the garlic and the ground beef. Season with salt and pepper. Break up the beef and mix with the veggies as it cooks.
When the beef is fully cooked (no pink meat), pour in the tomatoes. Stir to incorporate and reduce the temperature to medium low and simmer for about 20 minutes until the mixture starts to thicken.
At this point this 'base' can be cooled and frozen or continue to add more ingredients as you like. See suggestions in Notes.
