The Story Behind This Recipe
Here’s why I love this Pickled Pepper and Onion Relish: it uses pantry staples and it tastes like a bakery treat. Pickled Pepper and Onion Relish, oh my word. You ever stare at a boring sandwich and think, “This thing needs some serious flavor rescue”? Yup, me…
What is Pepper & Onion Relish Used For?
Let’s clear this up first, because I get asked all the time. Pickled Pepper and Onion Relish isn’t just for hot dogs, though it does make a regular dog taste like you got it from an old-timey ballpark. I use this relish on grilled cheese to make it less sad and more legendary. Sandwiches, of course, but don’t overlook tacos, scrambled eggs, or even a spoonful dumped into a bowl of soup for tangy magic. Oh, and cheese boards. Just trust me. It sits next to cheeses and makes crackers vanish like a card trick.
Sometimes, I’ll scoop it onto roasted potatoes and it’s like a flavor explosion. A humble bowl of rice? Life gets exciting if you toss a spoonful of this stuff on top. Family barbecue? This relish disappears faster than you can ask, “Who brought the good potato salad?” I even caught my cousin, Jamie, eating it straight from the jar last Thanksgiving. Not even mad about it.
“This relish has officially replaced ketchup at our house. I put it on everything, and I mean everything.” – Michelle, sandwich enthusiast

How to Make Onion & Pepper Relish
Alright, you ready? Here’s how I do it. No fancy skills required.
First, slice up your favorite sweet onions and a nice mix of bell peppers. Throw in something spicy if you’re feeling brave. You’ll want to grab some vinegar (white or apple cider, your call), a bit of sugar, and salt. Some folks add mustard seeds or garlic. I’ve tried both. It works but don’t stress if your spice rack’s looking thin.
Chuck everything into a saucepan, heat it up until it starts bubbling, and then simmer a bit. You want the veggies soft but not mush. That’s the sweet spot. Ladle it all into clean jars (I use old pickle jars sometimes, is that bad?) and let it cool. Refrigerate. Done.
Promise, your kitchen’s gonna smell like you invited a chef over. People will wander in saying, “What’s that smell?” and it’ll be this. And you made it—with, like, no effort.

Nutrition Facts (per serving)
I’m no dietician, but here’s what you actually want to know. Pickled Pepper and Onion Relish, per tablespoon, isn’t gonna blow your calorie budget. It’s mostly veggies, so it’s light—about 10-20 calories, almost zero fat, a little bit of sugar. There’s vitamin C, thank the peppers, and some fiber from onions. A little sodium (hello, pickling) but nothing to worry about unless you dump half a jar on your food. Honestly, for what you get in taste, it’s a trade-off. Oh, and if you want it less sweet, just ease back on the sugar when cooking.
Don’t let “pickled” fool you. It’s mostly good stuff in the jar.
